Download: https://www.jruby.org/download

JRuby 10 is finally here! We’ve jumped to Ruby 3.4 compatibility and Java 21 minimum to bring you the best Ruby on JVM experience possible. We are confident this is the most compatible and stable major release we’ve ever had.

Our blog post on JRuby 10 provides a high-level overview of the major changes, with some additional details below. We will update the blog post with additional detailed articles over the coming weeks: https://blog.jruby.org/2025/04/jruby-10-part-1-whats-new

As with any “dot zero” release, we are planning a series of quick updates to address any last-minute issues that snuck into the release. Please file bugs for any issues you see while testing JRuby 10.0: https://github.com/jruby/jruby/issues

Contributors

The JRuby core team today includes Charles Oliver Nutter (@headius), Thomas Enebo (@enebo), and Karol Bucek (@kares). Over the past year we have been honored to accept contributions from many other developers, and JRuby 10 would not be as stable or complete without their help:

@andsel, @mrnoname1000, @ahorek, @evaniainbrooks, @edipofederle, @ccutrer, @danini-the-panini, @ntkme, @andrykonchin, @mohamedhafez, @jsvd, @jpcamara, @mullermp, @ikaronen-relex, @jimtng, @ryannevell, @eregon, @moste00, @sk757a

Ruby Compatibility

Ruby compatibility has been updated to Ruby 3.4. We consider this release equivalent to Ruby 3.4.2.
Most features of Ruby 3.2, 3.3, 3.4 are complete, but some are still in progress. See our checklists based on CRuby’s release notes: Ruby 3.2, Ruby 3.3, Ruby 3.4
Except where a more recent gem was available or a library is unsupported by JRuby, we have included the same standard libraries as Ruby 3.4.

Java 21

After nearly a decade of supporting Java 8, the JRuby team decided it’s time for us to move to a more modern version of Java. The new requirement of Java 21 will allow us to take advantage of many features that were impossible to utilize while simultaneously supporting Java 8:

On-by-default optimization using InvokeDynamic, which has significantly improved since Java 8.
Support for thousands of Fibers using the lightweight virtual thread support from Project Loom.
Fast native function calling and native memory management using Project Panama.
Greatly improved startup time using Application Class Data Store, enabled by default by our launcher executables.
Easier access to post-Java 21 features like the Ahead-of-time compiler cache in Project Leyden.

Upgrading to JRuby 10

This release marks a big leap forward for JRuby users, and we are standing by to help with your transition from JRuby 9.x or migration from CRuby. Support services are available to help migrate your critical applications. Many existing users trust JRuby Support by Headius Enterprises to keep their applications in peak condition and to prepare for future updates.

Ruby Compatibility

Fixed a NegativeArraySizeException crash parsing heredocs. #8355, #8557
Users can now opt into Ruby 3.3 behavior for NoMethodError and NameError that no longer inspects the target object. This inspect frequently led to memory issues. Specify JRuby flag -XnameError.inspect.object=false or JVM property jruby.nameError.inspect.object=false to disable the inspect call. #216, #8384, #8538
Implemented the missing Process.argv0 method, used by recent Bundler releases. #8568, #8570

Standard Library

The jar-dependencies gem, responsible for fetching jar file dependencies of Ruby gems, can now be updated independently of JRuby. #7262, #8488, #8502
An upcoming release of jar-dependencies, will fix issues sourcing jar dependencies in container deployments (partially fixed previously by an updated ruby-maven-libs gem). #7059, #8366
The psych gem is updated to version 5.2.3, including a fix for YAML aliases from SnakeYAML-Engine version 2.9. #8352, #8575

Implementing a Java interface no longer leads to constant redefinition warnings. #8349, #8503
Precompiled Ruby scripts now properly prepare optimized homogeneous case/when statements. Previously they would deserialize incorrectly and garble the branches. #8421, #8424

Performance and Usability

Additional runtime data structures are eagerly cleared when tearing down a JRuby runtime, aiding GC. #8343, #8566
The JRuby shell-based launcher script now properly handles JRuby installed in a path with spaces. #8441, #8442
The Class#subclasses method has been optimized to eliminate it as a bottleneck in complex ActiveRecord STI queries. #8457, #8462
Integer multiplication operations that overflow outside of int64 range have been optimized to eliminate heavy exception raises. #8516, #8523

Java Integration

The “lazy” constants feature for classes imported from Java, introduced in JRuby 9.4.8.0, has been reverted due to spurious warnings. We’ll revisit it in a future release. #8349, #8368, #8399, #8400, #8401
Functions were added to allow flushing out thread-local and fiber-local storage for an entire JRuby runtime. #8369

Ruby Compatibility

Compatibility is updated to Ruby 3.1 level. This includes all Ruby 2.7, 3.0, and 3.1 features except where noted below. (#6464, #6878, #7015)
- Ractor is not yet supported. JRuby users can achieve better parallelism by using threaded libraries and frameworks.
- The scheduler interface for IO, locks, and fibers is not yet supported. It will be added in an update release.
Nearly all features from CRuby’s NEWS file have been implemented. Most new tests and specs pass.
Remaining 3.0 and 3.1 features will be implemented in an update release. See #7459 and #7460.

Standard Library

Much of the standard library has moved out to gems, and JRuby supports a large subset of these gems. See lib/pom.rb for the complete list of default and bundled gems.
Greatly improved PTY and spawn support thanks to the subspawn gem, which is included as part of the standard library. #7393

JVM Integration

Java setFoo methods that do not match JavaBean standards (return value other than void, for example) will now also generate a foo= method when imported into Ruby. (#7340, #7352)

Platform Support

The JRuby launcher script has been ported to POSIX shell (/bin/sh) and no longer requires Bash. (#7024)
Initial support for the LoongArch64 platform has been inherited from the Java Native Runtime libraries.

Third-party Libraries and Frameworks

Initial support for Rails 7. SQLite and MySQL are largely functional, but work remains to update them and PostgreSQL.

Ruby Compatibility

define_singleton_method now always uses public visibility. This simplifies its implementation and eliminates warnings when aliasing it, as in the ostruct gem. (ruby/ostruct#40, #7031, #7055)

Java Integration

The import method for importing Java classes remains deprecated for removal in 9.4, but now provides a better warning with a source location. (#6976)
Ruby subclasses of Java classes and Ruby classes converted into Java classes can now include instance variables that are accessible from Java as normal fields. This improves integration with Java frameworks that use reflection to access object state. (#7012)

Hardware Support

Generated make files now properly set the platform architecture when running on Linux/aarch64 and Apple’s M1 family of CPUs. This allows sassc and other non-extension C-based gems to build and install properly. (sass/sassc-ruby#231, #7132, #7133)

Standard Library

ostruct is updated to 0.5.1, which fixes warnings in verbose mode loading the json library. (#6831, #6963)
logger is updated to 1.5.1, which fixes a log rotation locking issue on Windows. (ruby/logger#67, ruby/logger#68, #7038)
Socket IPv6 constants are now always defined regardless of platform support, matching CRuby and JRuby 9.2. (#7069, #7071)

The big news this release is support for Apple’s M1 family of processors (Apple Silicon) via an update to our native FFI backend library. Nearly all our usual test suites are passing on M1 and we have added a self-hosted CI runner thanks to MacStadium’s OSS program. Callbacks from C to Ruby are unsupported, but this does not affect any libraries we ship. We will continue to improve M1 support with your help and bug reports.

We encourage users to file issues first and ask questions later! Please join our Matrix room if you have any issues or just want to get involved.

Thanks to our contributors this cycle for helping to improve compatibility: @ahorek, @byteit101

Additional thanks to @kovyrin for working through M1 issues with us and confirming that a large application builds and tests successfully.

Hardware Support

This release includes greatly improved support for Apple Silicon processors like the M1. (#6813, #6853, #6974, #6977, #6983, #6986, #7006)
Known issue: passing a Ruby FFI Function object to C code as a callback is not currently supported due to security restrictions on Apple Silicon. Neither JRuby nor any libraries we ship require this functionality. We will fix it for a future release. (#6995)

Ruby Compatibility

The parser once again handles files larger than 32k lines. This issue affected simplecov and mailer gems that we know of. (#6984, #6991)

Standard Library

ostruct is updated to 0.5.1, which fixes warnings in verbose mode loading the json library. (#6831, #6963)

Java Integration

Additional fixes for super calls from Ruby subclasses of Java classes to match behavior in 9.2.x. (#6935, #6957)

JRuby 9.3.x is compatible with Ruby 2.6.x and stays in sync with C Ruby. As always there is a mix of miscellaneous fixes so be sure to read the issue list below.

Security

Date-parsing methods have been modified to accept an input-size limit option. This addresses CVE-2021-41817. It was originally reported against Ruby’s C-based date extension, which JRuby does not use, but JRuby’s own implementation of date is also affected by the same issue.

The fix is detailed in #6952. A workaround is provided, via patching the pure-Ruby date code in your own JRuby install. Rebuilding JRuby is not necessary.
In order to match Ruby behavior and permit interrupting these date-parsing regular expression matches, this release also enables interruptible regular expressions globally. This feature can be disabled using the “regexp.interruptible” JRuby option as described in the above PR.

Performance

The performance of Time#strftime has been greatly improved (3.5x-5.8x faster). (#6942, #6956)

Native Integration

The jffi library on MacOS has been updated to sign the native library, allowing it to load properly on Apple Silicon. This improves compatibility on Apple’s AArch64 systems (M1 and friends). (jnr/jffi#116, jnr/jnr-ffi#257)

This is a security release to address CVE-2021-41817. It was originally reported against Ruby’s C-based date extension, which JRuby does not use, but JRuby’s own implementation of date is also affected by the same issue.

The issue affects calls to various Date and DateTime parsing methods with extremely long strings. The regular expressions associated with these methods may run much longer than desired or never return.

The fix is detailed in #6951. A workaround is provided, via patching the pure-Ruby date code in your own JRuby install. Rebuilding JRuby is not necessary. This PR is the only functional difference from JRuby 9.2.20.0.

We recommend that all JRuby 9.2 users upgrade.

Native Integration

The built-in FFI library has been updated to match the FFI gem, and can now be upgraded independently of JRuby. (#6732, #6747)
FFI-based core methods on Windows and Solaris have been modified to delay activating FFI until after RubyGems has loaded any upgrades. (#6751, #6760, #6762)

Java Integration

Nested jar files (jars packaged within another application jar) should load more quickly with caching improvements. (#6730, #6734, #6740)

JRuby would not be successful without your help: @ahorek, @byteit101, @chrisseaton, @deivid-rodriguez, @edipofederle, @JasonLunn, @joshbressers, @k77ch7, @MariuszCwikla, @marshalium, @MikaelUrankar, @mkristian, @nomadium, @olleolleolle, @pirj, @ProfessorEugene, @pzygielo, @T45K, @thbar

These notes may be updated on the JRuby Wiki to include additional information and links to new or updated documentation: JRuby 9.3.0.0 Release Notes

Compatibility

Ruby language compatibility is updated to match Ruby 2.6.8. (#5576)
The require/load/autoload subsystem has been rewritten to better match Ruby behavior. This improves support for the Zeitwerk loader and fixes many long-standing issues. (#2794, #3656, #5403, #5466, #5590, #5618, #5638, #5717, #5763, #5764, #6347, #6445)
Improved logic for handling complex method and constant lookups, such as when prepends, refinements, or super calls are in play. Most known issues with these forms have been fixed. (596, #2155, #4678, #6271, #6712, #6777, #6778, #6785)

Standard Library

The standard library has been updated to match Ruby 2.6.8. Several libraries now use the official gems, allowing them to be upgraded independently of JRuby. (#4875, #6150, #6797, #6796, #6795, #6794, #6533, #6802)

Java Integration

JRuby supports Java versions 8 through 17, and should work well with any supported build of OpenJDK. Future versions of JRuby may drop support for Java 8 through 10, so we encourage users to upgrade older apps soon.
The Java integration logic for extending Java classes from Ruby has been rewritten to better support Java constructors and to reuse more logic from the rest of our Java integration library. This allows users to use those Ruby subclasses with Java frameworks that bootstrap using reflection, such as JavaFX. (#449, #2369, #4165, #5270, #6422)
JRuby now ships a new “jruby-base” jar artifact to Maven Central. This artifact provides a bare-bones JRuby jar file with no dependencies or standard libraries included. We may deprecate and remove the “jruby-core” artifact in the future, as it only provides Java dependencies and no standard libraries (users should prefer to build their own with jruby-base or use the jruby-complete artifact). (#6233)

The JRuby community is pleased to announce the release of JRuby 9.2.19.0

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

JRuby 9.2.x is compatible with Ruby 2.5.x and stays in sync with C Ruby. As always there is a mix of miscellaneous fixes so be sure to read the issue list below. All users are encouraged to upgrade.

As we are still actively working on 9.3.0.0 we decided to put out another 9.2.x release to fix some of the more recently reported issues.

Thanks to contributor @ahorek for a couple quick-fix PRs this release!

Native Integration

Work around a bug in our backend FFI library, jnr-ffi, that broke calls to getsockopt or setsockopt in --dev mode. (#6714, #6723)

Windows Support

Honor the TZ environment variable when applying a timezone to file modification/access/create times. (#6659, #6720)

Github Issues resolved for 9.2.19.0

#6714 - getsockopt crashing with 9.2.18.0 and JRUBY_OPTS=--dev flag
#6720 - File#mtime fix timezone
#6723 - getsockopt crash in --dev mode

As we are still actively working on 9.3.0.0 we decided to put out another 9.2.x release to fix some of the more recently reported issues.

Compatibility

Several issues were fixed in process management, to avoid raising unexpected errors, properly launch executables on Windows, and preserve quoting when also doing a chdir. (#6466, #6477, #6489, #6516, #6532, #6536, #6546, #6565, #6568)
Error and interrupt handling inside fibers has been improved to avoid leaking fibers and enumerators. (#6309, #6538)
An incompatibility between the Synchronized module and refinements caused the i18n gem’s deep_merge refinement to break method lookup and prevent Rails apps from starting up. (#6547, #6549)
IO.copy_stream attempted to write the same content twice when copying to an IO-like object that did not report having written all requested bytes. (#6555, #6557)
Bare super calls (aka “zsuper”) gathered arguments incorrectly to support define_method, which broke dynamic finders in recent Rails versions. (#6563, #6571)

Standard Library

The racc library was updated to 1.5.2 (#6507, #6517, #6537)
Failed UNIX socket connects were leaking an open file descriptor. (#6529, #6531)

Performance

A bug in setting up block yields using invokedynamic led to excessively deep call stacks and slow execution. (#6260)

jruby-openssl was updated to 0.10.5 to eliminate some Java module warnings and improve compatibility. (#6423)

Concurrency

A race in storing the lock a thread has just acquired was fixed, preventing that lock from being left locked if the thread dies prematurely. (#6326, #6405, #6407)

Performance

Call sites bound using invokedynamic were not inlining due to a quirk of classloading on OpenJDK. This has been fixed so such calls inline properly. (#6280)

Native Integration

As we are still actively working on 9.3.0.0 we decided to put out another 9.2.x release to fix some of the more recently reported issues.

Security

An alias-expansion bug reported in CVE-2017-18640 has been patched by upgrading the Psych YAML library to use a newer version of SnakeYAML. (#6320, #6332, ruby/psych#457)

Concurrency

Internal structures used to optimize Ruby code have been made more thread-safe. Previously, these optimizations could be seen across threads in a partially-complete state, leading to errors in JRuby’s core runtime. (#6319, #6323, #6337)

Ruby Compatibility

IO.copy_stream has been fixed to ensure all read bytes are written. Previously, partial writes would leave some read bytes in limbo, leading to hangs in net/http among other libraries. (#6078, #6348)
Fixed a regression from 9.2.12.0 in how we translate JDK socket errors to Ruby’s Errno on Windows. (#6322, #6328)

FFI

FFI has been patched to not automatically release memory pointers when autorelease is disabled. This caused crashes in the sassc native library and possibly others. (#6310, #6331)
12 issues fixed for 9.2.13.0

Github Issues resolved for 9.2.13.0

JRuby 9.2.x is compatible with Ruby 2.5.x and stays in sync with C Ruby. As always there is a mix of miscellaneous fixes so be sure to read the issue list below. All users are encouraged to upgrade.

As we are still actively working on 9.3.0.0 we decided to put out another 9.2.x release to fix some of the more recently reported issues.

Java Integration

The last remaining triggers of the “Illegal access” warnings and errors in JRuby core have been fixed. JRuby will avoid accessing Java modules and packages that have not been exported or opened. (#6195, #6287, #6298, #6299)
A new option is added to work around the OpenJDK URLClassLoader concurrency bug we recently reported. Set Java property jruby.ji.close.classloader to false when embedding JRuby in a JVM application to avoid “zip file closed” errors. This will be the default setting in JRuby 9.3. (#6218, #6307)
Support for calling Kotlin has improved, avoiding warniings for companion objects. This also avoids a warning when accessing Java code where a static final field is named the same as an inner class. (#6196, #6289)

Concurrency

An issue affecting concurrent generation of Java interface implementations has been fixed. (#6160, #6167)
Internal optimization of Ruby code has been improved to avoid concurrency issues. (6210, #6230, #6275, 6282, #6288)

Security

A few minor security issues have been fixed. We do not consider them high risk, but we recommend users update. (#6304)

Numeric objects now use a per-runtime random seed to generate hash values (CVE-2011-4815). The existing JRuby property jruby.consistent.hashing can be set to true to restore predictable hash values, as for other core types. (6305)
String#unpack raised the wrong error for invalid input related to CVE-2018-8778. There was no security issue. (#6306)
The WEBrick HTTP server provided in the Ruby standard library has been updated to 1.6.0, to address two issues with response-splitting and header injection (CVE-2017-17742 and CVE-2019-16254). This server is not typically used in production, so the exposure is limited. (#6308)

24 Github Issues resolved for 9.2.12.0

#6308 - Update WEBrick to 1.6.0
#6307 - Only close temporary jars to avoid poisoning global jar file cache
#6306 - Raise RangeError for out of bounds unpack_at
#6305 - Mimic CRuby's numeric hashing
#6304 - Align behavior with CRuby for security specs

JRuby 9.2.x is compatible with Ruby 2.5.x and stays in sync with C Ruby. As always there is a mix of miscellaneous fixes so be sure to read the issue list below. All users are encouraged to upgrade.

As we are actively working on 9.3.0.0 we decided to put out a mini release which fixes a single issue.

sprintf substring string formatting with precision may expose characters (#6137)

If you format a string using a precision specifier (e.g. %.1s) AND you pass in a substring of a larger string, you may see some of the larger string’s characters in the formatted result. This is due to a bug in the handling of internal String data that causes the result to contain more characters than requested.

long_string = "aabbccddhelloddccbbaa"
start_index = 8
sub_str_length = 5
precision = 3
sub_string = long_string[start_index, sub_str_length]
puts sprintf("%.#{precision}s", sub_string)
# => helloddccbb

This bug could potentially expose sensitive content from the original String. It is unlikely to affect most users, but you are still encouraged to upgrade.

Github Issues resolved for 9.2.11.1

#6138 - Subtract begin offset for partial substring in sprintf 's'
#6137 - `sprintf` adds extra buffer slots when precision arg truncates string slices

More illegal access warnings have been cleaned up in JRuby and the jruby-openssl extension.

Native FFI Improvements

The native subsystem has been rebuilt on MacOS to avoid security warnings due to the old toolchain originally used to build it. (#6044, #6074)
Native constants have been updated for Windows to better support the Ruby socket API. (#5656, #6070, #6071)

Performance Improvements

Several improvements to the method invocation pipeline and JVM bytecode output to improve JIT optimizations. (#5958, #5959, #5978, #5992, #6005)
Several core methods used by Rails and the internal handling of exception backtraces have been optimized. (#5952, #5961, #5965, #5972, #6014, #6015, #6031, #6067)

JRuby Launcher

Java options dotfiles accidentally omitted in the JRuby 9.2.9.0 release have been restored in the bin directory.

The JRuby community is pleased to announce the release of JRuby 9.2.9.0

Homepage: http://www.jruby.org/
Download: http://www.jruby.org/download

JRuby 9.2.x is compatible with Ruby 2.5.x and stays in sync with C Ruby. As always there is a mix of miscellaneous fixes so be sure to read the issue list below. All users are encouraged to upgrade.

Ruby Standard Library

The Ruby Standard Library has been updated to Ruby 2.5.7. JRuby will now report this as our equivalent compatible Ruby version. (#5917)
RubyGems has been updated to version 2.7.10.

Security Updates

This release removes an exploitable version of JQuery used by the rdoc library. See https://www.ruby-lang.org/en/news/2019/08/28/multiple-jquery-vulnerabilities-in-rdoc/

Java Modules Support

Java modules are better supported in this release by checking for openness before attempting to reflect against classes from that module. This should reduce the number of module warnings on Java 9+ and make it easier to configure the JVM to open up appropriate modules and packages to JRuby applications. See also the .jruby.java_opts file below, which can help you manage module options. (#5841, 5832, #5843, #5855, #5860)

Java Launcher Improvements

JVM options can now be added to global or app-local .jruby.java_opts files and automatically processed by the JRuby launcher. See JRuby Java Options Files for more information. Note: This feature is not yet supported by the JRuby native launcher, installed by default in RVM. We will release an update to the native launcher soon. (#5824, #5826)
You can now pass --environment to the JRuby launcher to get a log of exactly how we will execute your application. (#5840)
JRuby’s dev mode (via the --dev flag) adds additional options for Java 9+ and the OpenJ9 JVM. On OpenJ9, the -Xquickstart and -Xshareclasses flags are passed via the OPENJ9_JAVA_OPTIONS environment variable. (#5831)

Memory Usage Reductions

Numerous changes in this release reduce the boot-time and run-time memory use of JRuby applications. (#5837, #5832, #5874, #5880, #5885)

Thread-safety Improvements

Lock interruptibility broken in JRuby 9.2.8 has now been fixed. (#5863, #5875, #5942)

Process.wait APIs are now interruptible

Threads calling Process.wait, waitall, or waitpid will use the pthread_kill native function to interrupt those operations. Previously these threads were not interruptible. (#1050, #5848)

Native FFI improvements

When running JRuby via the “complete” jar file, we must unpack our native FFI stub to an appropriate temporary location. If the default location we use (the host system’s default “temp” location) is not readable or does not allow executable code, we will present an informational error indicating how to correct the issue. (#1302)
This release also includes native support for DragonFly BSD. (#5768, #5828)

Time Zone Data

Time zone data has been updated to IANA 2019c. This update includes six years of timezone changes. (#5951)

Download: https://www.jruby.org/download

JRuby 9.2.x is our new major version of JRuby. It is expected to be compatible with Ruby 2.5.x and stay in sync with C Ruby. JRuby 9.2.0.0 is our first release for 2.5 support.

If you do find issues then report them on using our issue tracker at https://github.com/jruby/jruby/issues. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

This is a security release that updates the native Windows executables shipped in the bin directory. A user reported that several virus scanners appear to flag one of these executables, jrubyw.exe, as containing a virus. We scanned the systems used for building those executables, and were unable to find any evidence of infection, but as a precaution we have rebuilt them on a known clean system for this release.

Truffle

JRuby 9000 includes an preliminary version of support for the Truffle language implementation framework and Graal JIT compiler from Oracle Labs. In future releases, Truffle will provide an extremely high performance and compatible backend for JRuby. The Truffle backend supports almost all Ruby language features and the majority of the core library, and is able to run simple gems and web frameworks such as Sinatra. It has no support for RubyGems, Rails or any database drivers, and does not work on Windows. However we are now interested in people submitting issues for small gems with minimal dependencies who see issues running on JRuby+Truffle

Graal has been integrated into Java 9 early access builds, and can be used today as part of the GraalVM, which is currently the recommended way to run JRuby+Truffle.

More information on Truffle and Graal can be found in the JRuby Wiki.

The JRuby community is pleased to announce the release of JRuby 1.7.26

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

JRuby 1.7.26 is our thirtieth update release since JRuby 1.7.0. The primary goal of 1.7 point releases is to fill out any missing compatibility issues with Ruby 1.9.3.

PSA: Over the years we have had Windows CI support and then lost Windows CI supprt. We would still irregularly run tests on windows, but this is never as good as getting more immediate feedback. Via the ability to use an awesome service like ci.appveyor.com, we are again regularly running against a Windows CI. If you peruse the list of resolved issues you will see how important it is to be regularly running CI on all the OSes you support.

Highlights:

8 issues fixed for 1.7.26

The JRuby community is pleased to announce the release of JRuby 9.1.2.0

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

JRuby 9000 is the newest major version of JRuby, representing years of effort and large-scale reboots of several JRuby subsystems. It is expected to be compatible with Ruby 2.x and stay in sync with C Ruby. JRuby 9.1.2.0 is our latest release…

Major features of JRuby 9000:

Ruby 2.x compatibility
A new optimizing runtime based on a traditional compiler design
New POSIX-friendly IO and Process
Fully ported encoding/transcoding logic from MRI

If you do find issues then report them on using our issue tracker at https://github.com/jruby/jruby/issues. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

Notable updates since 9.1.1.0

5 issues fixed for 9.1.2.0

Truffle

JRuby 9000 includes an preliminary version of support for the Truffle language implementation framework and Graal JIT compiler from Oracle Labs. In future releases, Truffle will provide an extremely high performance and compatible backend for JRuby. The Truffle backend supports almost all Ruby language features and the majority of the core library, and is able to run simple gems and web frameworks such as Sinatra. It has no support for RubyGems, Rails or any database drivers, and does not work on Windows. However we are now interested in people submitting issues for small gems with minimal dependencies who see issues running on JRuby+Truffle

Graal has been integrated into Java 9 early access builds, and can be used today as part of the GraalVM, which is currently the recommended way to run JRuby+Truffle.

More information on Truffle and Graal can be found in the JRuby Wiki.

Github Issues resolved for 9.1.2.0

The JRuby community is pleased to announce the release of JRuby 9.0.4.0

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

JRuby 9000 is the newest major version of JRuby, representing years of effort and large-scale reboots of several JRuby subsystems. It is expected to be compatible with Ruby 2.2.x and stay in sync with C Ruby. JRuby 9.0.4.0 is our third of many point releases…

9.0.4.0 is a quick turnaround release to address some problems with the new stat() implementation on windows and couple of issues. We have a lot more confidence in the new stat code now. In addition, we addressed a fairly long-standing memory leak with stat() on windows. A followup release for 1.7.23 will also be out soon to address the same leak (next week).

Major features of JRuby 9000:

Ruby 2.2 compatibility
A new optimizing runtime based on a traditional compiler design
New POSIX-friendly IO and Process
Fully ported encoding/transcoding logic from MRI

If you do find issues then report them on using our issue tracker at https://github.com/jruby/jruby/issues. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

Notable updates since 9.0.3.0

Resolved various issues with stat() on Windows
Fixed couple of encoding/transcoding issues
Source with __FILE__ in it will now JIT
Native call subsystem will load on mixed 32/64 bit Linux distributions
11 issues fixed for 9.0.4.0

Truffle

JRuby 9000 includes an preliminary version of support for the Truffle language implementation framework and Graal VM from Oracle Labs. In future releases, Truffle will provide an extremely high performance and compatible backend for JRuby. The Truffle backend supports almost all Ruby language features and the majority of the core library, and is able to run simple gems and web frameworks such as Sinatra. It has no support for RubyGems, Rails or any database drivers, does not work on Windows, and is not ready to be tested with applications at this stage. More information on Truffle and Graal can be found in the JRuby Wiki.

Github Issues resolved for 9.0.4.0

#3457 - stat.st_gid is unsupported on windows
#3449 - jirb fails to start on Windows
#3448 - File.stat("someunavailable").mtime returns odd result

#3408 - IRB fails to start with JRuby9.0.3.0 on Windows 10.
#3197 - require_relative fails for relative paths within jars on Windows
#2381 - IO#rewind ... doesn't. (when backed by a ByteArrayInputStream).

[NOTE: 9.0.2.0 was prematurely released to Maven with a serious issue so we had to skip putting out a 9.0.2.0 release (Maven does not allow replacing pushed artifacts). So 9.0.3.0 is our second official point release. We apologize for any confusion this may cause.]

Read our blog entry on JRuby 9000 for more information.

We finally made it to 9.0.0.0. As the flood gates open and we get some people trying this new major version for the first time we expect to get a stream of issue reports. JRuby 9k should be stable and production ready but real world users hitting it for the first time generally uncovers new issues. Because of this, we expect to fairly quickly have followup point releases.

If you do find issues then report them on using our issue tracker at https://github.com/jruby/jruby/issues. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

It is important to point out that when we do put out JRuby 9.0.0.0 that this is only the starting point. Our new internals gives us lots of potential to keep pushing the bar higher on JRuby performance.

Notable updates since rc2

Two reverts on classloading to restore behavior to be like JRuby 1.7.x
Non-lambda return passing through a lambda could return improperly
Fixed two visibility issues on methods (#3123, #3135)
39 issues fixed for 9.0.0.0 (note: some issues in list predate rc2 release)

Truffle

JRuby 9000 includes an preliminary version of support for the Truffle language implementation framework and Graal VM from Oracle Labs.

The Truffle backend supports almost all Ruby language features and the majority of the core library, and is able to run simple gems and web frameworks such as Sinatra.

We are hoping this is our last release candidate before JRuby 9.0.0.0. The severity of problems are getting small enough where we think the next release will be 9.0.0.0.

If you do find issues then report them on using our issue tracker at https://github.com/jruby/jruby/issues. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

It is important to point out that when we do put out JRuby 9.0.0.0 that this is only the starting point. Our new internals gives us lots of potential to keep pushing the bar higher on JRuby performance.

Notable updates since rc1

Fixed cases where AOT classes were not loading
Various performance fixes
Reduced memory size
More parser fixes
Fixed rc1 eval with binding regression (aka setValueDepthZero AIOOB)
39 issues fixed for 9.0.0.0.rc2

Truffle

JRuby 9000 includes an preliminary version of support for the Truffle language implementation framework and Graal VM from Oracle Labs. In future releases, Truffle will provide an extremely high performance and compatible backend for JRuby. The Truffle backend supports almost all Ruby language features and the majority of the core library, and is able to run simple gems and web frameworks such as Sinatra. It has no support for RubyGems, Rails or any database drivers, does not work on Windows, and is not ready to be tested with applications at this stage. More information on Truffle and Graal can be found in the JRuby Wiki.

JRuby 9000 is the new version of JRuby, representing years of effort and large-scale reboots of several JRuby subsystems. It is expected to be compatible with Ruby 2.2.x and stay in sync with C Ruby.

Major features of JRuby 9000:

Ruby 2.2 compatibility
A new optimizing runtime based on a traditional compiler design
New POSIX-friendly IO and Process
Fully ported encoding/transcoding logic from MRI

This release is approaching a level of compatibility and stability where we have moved into a release candidate stage. We will address concerns reported before going final, so now is the time to find any problems…

If you do find issues then report them on using our issue tracker at https://github.com/jruby/jruby/issues. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

It is important to point out that when we do put out JRuby 9.0.0.0 that this is only the starting point. Our new internals gives us lots of potential to keep pushing the bar higher on JRuby performance.

JRuby 9000 is the new version of JRuby, representing years of effort and large-scale reboots of several JRuby subsystems.

Major features of JRuby 9000:

Ruby 2.2 compatibility, minus features listed below
A new optimizing runtime based on a traditional compiler design
New POSIX-friendly IO and Process
Fully ported encoding/transcoding logic from MRI

This is our second preview release, and we are getting much closer to reaching our first .0 release. We are releasing this update to get user feedback on Ruby 2.2 functionality and overall stability.

We hope all Ruby users will try out this release and report issues on our issue tracker at https://github.com/jruby/jruby/issues. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

Ruby 2.2 features yet to be implemented:

Refinements (partially finished) #1062
Kernel#spawn close-on-exec support
ObjectSpace::WeakMap#each and Enumerable inclusion
Thread#handle_interrupt is not yet fully functional

Notable changes since pre1:

Startup time has improved but is a tiny bit slower than 1.7.x.
Memory usage has improved but still a ways to go.
Straight-line performance has improved since pre1
Windows support improved, but still needs further work and testing
Many keyword arguments problems fixed
88 issues fixed for 9.0.0.0.pre2

The new runtime gathers more information about Ruby code and performs more analysis and optimization than our old runtime. There’s great potential here to bring Ruby performance to native Java or C, but we are just starting the optimization phase of that work. We will do our best to get startup time, memory use, and performance on par with 1.7.x (or better) before the final release of JRuby 9000.

Truffle

JRuby 9000 includes an in-development version of support for the Truffle language implementation framework and Graal VM from Oracle Labs. In future releases, Truffle will provide an extremely high performance and compatible backend for JRuby. The Truffle backend supports all Ruby language features, but so far only some of the core and standard libraries. It has no support for RubyGems or Rails, does not work on Windows, and is not ready to be tested with applications at this stage. More information on Truffle and Graal can be found in the JRuby Wiki.

The JRuby community is pleased to announce the release of JRuby 9.0.0.0-pre1

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

JRuby 9000 is the new version of JRuby, representing years of effort and large-scale reboots of several JRuby subsystems.

Major features of JRuby 9000:

Ruby 2.2 compatibility, minus features listed below
A new optimizing runtime based on a traditional compiler design
New POSIX-friendly IO and Process
Fully ported encoding/transcoding logic from MRI

This is a preview release, and we know there’s work to do. We are releasing now to get user feedback on Ruby 2.2 functionality and overall stability.

We hope all Ruby users will try out this release and report issues on our issue tracker at https://github.com/jruby/jruby/issues. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

Ruby 2.2 features yet to be implemented:

Refinements #1062
Enumerator#feed
Kernel#spawn close-on-exec support
ObjectSpace::WeakMap#each and Enumerable inclusion
ObjectSpace::count_objects
Thread#handle_interrupt is not yet fully functional
POSIX-friendly IO, TTY, and Process logic is not used on Windows

We also have additional work to do on the new runtime:

Startup time is a bit slower.
Memory usage is higher.
Straight-line performance is a little bit slower.

The new runtime gathers more information about Ruby code and performs more analysis and optimization than our old runtime. There’s great potential here to bring Ruby performance to native Java or C, but we are just starting the optimization phase of that work. We will do our best to get startup time, memory use, and performance on par with 1.7.x (or better) before the final release of JRuby 9000.

Truffle

JRuby 9000 includes an in-development version of support for the Truffle language implementation framework and Graal VM from Oracle Labs. In future releases, Truffle will provide an extremely high performance and compatible backend for JRuby. The Truffle backend supports all Ruby language features, but so far only some of the core and standard libraries. It has no support for RubyGems or Rails, does not work on Windows, and is not ready to be tested with applications at this stage. More information on Truffle and Graal can be found in the JRuby Wiki.

This release was an insanely quick followup release to 1.7.7. We realized a few hours ago after releasing 1.7.7 that we accidentally shipped the MacOS bin/jruby binary launcher. JRuby 1.7.8 is essentially 1.7.7 with the single correction to our bin dist file.

JRuby 1.7.5 is our fifth update release since JRuby 1.7.0. The primary goal of 1.7 point releases is to fill out any missing compatibility issues with Ruby 1.9.3. The community participation lately has been great. Keep reporting issues and sending pull requests.

This release is a special point release in that it is the last point release before we move JRuby 1.7.x onto a maintenance branch. At this point we will put out more releases of 1.7.x based on bug reports, but a bulk of our effort will change to work on the next major version: JRuby 9000.

We fixed a number of issues with JRuby’s support for invokedynamic, but due to increased memory requirements and some lingering issues we have opted to leave it disabled until Java 8 (due in March). Users willing to bump up memory use (PermGen, specifically) can still enable invokedynamic via -Xcompile.invokedynamic=true. We also encourage users to try their apps on early access builds of Java 8.

This summer, the JRuby team and our community members mentored ten students on a wide range of projects as part of Google’s Summer of Code 2013.. We would like to thank Asakawa Ryu, Benoit Daloze, Chamila Wijayarathna, Devwrat More, Eric West, Faraaz Ismail, Kumar Sukhani, Maximilian Konzack, Matthew Getch, and Tobias Pfeiffer for participating and congratulate them on their excellent work.

From this point forward, all users should report issues on our https://github.com/jruby/jruby project site. You can also just go to https://github.com/jruby/jruby/issues.

243 issues fixed for 1.7.5

- Many many encoding/M17n issues resolved.
- Improved transcoding support
- Fiber fixes

We’re pleased to announce that JRuby has been accepted as a mentoring organization for Google Summer of Code 2013!

JRuby participated in last year’s Google Summer of Code with eight excellent students. Projects ranged from serialization of our new intermediate representation to improved Android support via the Ruboto project. We’re hoping to have another great batch of projects, students, and mentors this year.

The JRuby GSoC 2013 wiki page has all the practical details, including dates, contact information, and possible ideas. This week (until April 21) we’re looking for mentors interested in helping a student over the summer. From April 22 to May 3, students can submit their proposals, and soon after that we’ll get our slot allocations and select projects.

If you are interested in mentoring a project, now’s the time to get involved! Apply on the JRuby GSoC organization page. If you aren’t interested in mentoring, please pass the word on to others!

If you’d like to work on a project for JRuby as a student, you should start communicating with us on the jruby-gsoc Google Group today. We’ll help you find a project that suits you and make sure you put together a complete proposal after April 22. You’ll also apply on the JRuby GSoC organization page, but not until after April 21. If you’re not a student or won’t be able to participate…tell your friends we’re looking for them!

Google Summer of Code has been a really exciting and rewarding experience for the JRuby project, and we’re looking forward to another excellent year.

The JRuby community is pleased to announce the release of JRuby 1.7.3

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

Alert Please note the primary reason for putting out 1.7.3 was to address two security issues. Everyone should upgrade to 1.7.3 (details on security issues below).

Note: This was a condensed release due to wanting to put out security fixes. If the bugs you are waiting for have not been fixed we will be fixing them for 1.7.4.

JRuby 1.7.3 is our third update release since JRuby 1.7.0. The primary goal of 1.7 point releases is to fill out any missing compatibility issues with Ruby 1.9.3. The community participation lately has been great. Keep reporting issues and sending pull requests.

Changes of note:

Security fix (no CVE) for DOS using entity expansion in REXML
Security fix (CVE-2013-0269) for unsafe object creation using JSON
Relicensed from CPL to EPL
Fixed one regression in windows java native launcher
A few encoding issues resolved
42 issues fixed for 1.7.3

Note: These next two sections are write-ups by Aaron Patterson on the security issues. JRuby 1.7.3 fixes both of these issues. You only need to be aware of workarounds if it is impossible for you to update JRuby to version 1.7.3.

Rexml DOS Fix

Impact

When reading text nodes from an XML document, the REXML parser can be coerced in to allocating extremely large string objects which can consume all of the memory on a machine, causing a denial of service.

Impacted code will look something like this:

document = REXML::Document.new some_xml_doc
document.root.text

When the text method is called, entities will be expanded. An attacker can send a relatively small XML document that, when the entities are resolved, will consume extreme amounts of memory on the target system.

Note that this attack is similar to, but different from the Billion Laughs attack. This is also related to CVE-2013-1664.

All users running an affected release should either upgrade or use one of the work arounds immediately.

Workarounds

If you cannot upgrade Ruby, use this monkey patch as a workaround:

class REXML::Document
  @@entity_expansion_text_limit = 10_240

  def self.entity_expansion_text_limit=( val )
    @@entity_expansion_text_limit = val
  end

  def self.entity_expansion_text_limit
    @@entity_expansion_text_limit
  end
end

class REXML::Text
  def self.unnormalize(string, doctype=nil, filter=nil, illegal=nil)
    sum = 0
    string.gsub( /\r\n?/, "\n" ).gsub( REFERENCE ) {
      s = self.expand($&, doctype, filter)
      if sum + s.bytesize > REXML::Document.entity_expansion_text_limit
        raise "entity expansion has grown too large"
      else
        sum += s.bytesize
      end
      s
    }
  end

  def self.expand(ref, doctype, filter)
    if ref[1] == ?#
      if ref[2] == ?x
        [ref[3...-1].to_i(16)].pack('U*')
      else
        [ref[2...-1].to_i].pack('U*')
      end
    elsif ref == '&amp;'
      '&'
    elsif filter and filter.include?( ref[1...-1] )
      ref
    elsif doctype
      doctype.entity( ref[1...-1] ) or ref
    else
      entity_value = DocType::DEFAULT_ENTITIES[ ref[1...-1] ]
      entity_value ? entity_value.value : ref
    end
  end
end

This monkey patch will limit the size of the entity substitutions to 10k per node. REXML already defaults to only allow 10000 entity substitutions per document, so the maximum amount of text that can be generated by entity substitution will be around 98 megabytes.

JSON Security Fix CVE-2013-0269

Impact

When parsing certain JSON documents, the JSON gem can be coerced in to creating Ruby symbols in a target system. Since Ruby symbols are not garbage collected, this can result in a denial of service attack.

The same technique can be used to create objects in a target system that act like internal objects. These “act alike” objects can be used to bypass certain security mechanisms and can be used as a spring board for SQL injection attacks in Ruby on Rails.

Impacted code looks like this:

JSON.parse(user_input)

Where the user_input variable will have a JSON document like this:

{"json_class":"foo"}

The JSON gem will attempt to look up the constant “foo”. Looking up this constant will create a symbol.

In JSON version 1.7.x, objects with arbitrary attributes can be created using JSON documents like this:

{"json_class":"JSON::GenericObject","foo":"bar"}

This document will result in an instance of JSON::GenericObject, with the attribute “foo” that has the value “bar”. Instantiating these objects will result in arbitrary symbol creation and in some cases can be used to bypass security measures.

PLEASE NOTE: this behavior does not change when using JSON.load. JSON.load should never be given input from unknown sources. If you are processing JSON from an unknown source, always use JSON.parse.

All users running an affected release should either upgrade or use one of the work arounds immediately.

Workarounds

For users that cannot upgrade, please use the attached patches. If you cannot use the attached patches, change your code from this:

JSON.parse(json)

To this:

JSON.parse(json, :create_additions => false)

If you cannot change the usage of JSON.parse (for example you’re using a gem which depends on JSON.parse like multi_json), then apply this monkey patch:

module JSON
  class << self
    alias :old_parse :parse
    def parse(json, args = {})
      args[:create_additions] = false
      old_parse(json, args)
    end
  end
end

The JRuby community is pleased to announce the release of JRuby 1.7.1

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

JRuby 1.7.1 is our first update release since JRuby 1.7.0. The primary goal of 1.7 point releases is to fill out any missing compatibility issues with Ruby 1.9.3. The feedback we have gotten (along with patches) has ended up being a subtantial release.

We also addressed security vulnerability CVE-2012-5370 and stopped using MurmurHash2 as our hashing algorithm (now using same Hashing algorithm as Perl). All users are recommended to upgrade to JRuby 1.7.1.

Changes of note:

New hashing algorithm to address CVE-2012-5370
Update standard lib to match MRI patchlevel 1.9.3p327
Several fixes to new io/console.rb implementation
system/spawn/popen fixes and additional options hash fixes
Several SSL fixes (jruby-openssl release coming soon for 1.6.8 users)
IO.select not erroneously reporting data to be read
Psych YAML engine updated to latest
43 issues fixed since 1.7.0

The JRuby community is pleased to announce the release of JRuby 1.7.0

Homepage: https://www.jruby.org/

After a long journey (1.5 years..oh my) we have released JRuby 1.7.0. The JRuby 1.7 release series represents a tremendous amount of work by dozens of contributors, and there are improvements in every subsystem. Users of highly-concurrent applications will see improvements in throughput and raw parallelism. And JRuby now defaults to 1.9 mode, with compatibility level targeting Ruby 1.9.3.

We know that there are still pieces of 1.9 support we don’t have yet, like Ripper, but we are at a stable point where people can use JRuby in 1.9 mode to host production applications. At this point, we plan on putting out point releases of 1.7.x every 2-3 weeks for the foreseeable future. These point releases will be made to address any reported problems users run into; and also to fill out the few missing 1.9 libraries not yet finished.

JRuby 1.7 is the first JRuby to support the new “invokedynamic” feature of the JVM. You can enable invokedynamic use on Java 7, but it is disabled normally due to JVM issues. On Java 8 builds, it is enabled by default. https://github.com/jruby/jruby/wiki/PerformanceTuning

1.9.3 is now our default runtime mode (–1.8 is needed for 1.8.7 support)
Ruby standard library updated to 1.9.3p286
Many 1.9.x compatibility fixes
Support for invokedynamic
Performance and concurrency improvements throughout
Java 5 support dropped (Java 6+ required)
All known 1.9 encoding issues resolved
Kernel#exec now does a true native exec on all platforms
Improvements and fixes to Java integration and embedding
Native features now better supported on Solaris, ARM Linux, and others
Update to Rubygems 1.8.24
Update to Rake 0.9.2.2

The JRuby community is pleased to announce the release of JRuby 1.7.0.RC2.

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

This is the second (and likely last) release candidate of JRuby 1.7. The JRuby 1.7 release series represents a tremendous amount of work by dozens of contributors, and there are improvements in every subsystem. Users of highly-concurrent applications will see improvements in throughput and raw parallelism. And we have upped our compatibility level to match Ruby 1.9.3.

We know that there are still pieces of 1.9 support we don’t have yet, like Ripper, but we think we are at a stable point where people can use JRuby in 1.9 mode to host production applications. Barring any significantly serious issues, RC2 will become 1.7.0. Our plan after the release of 1.7.0 is a set of smaller point releases to address bugs and to add the few missing pieces of Ruby 1.9.

JRuby 1.7 is the first JRuby to support the new “invokedynamic” feature of the JVM. You can enable invokedynamic use on Java 7, but it is disabled normally due to JVM issues. On Java 8 builds, it is enabled by default. https://github.com/jruby/jruby/wiki/PerformanceTuning

Please, please, please test your applications against 1.7.0.RC2. We want to make 1.7.0 a rock solid release and your contribution is extremely helpful.

The JRuby community is pleased to announce the release of JRuby 1.6.8.

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

The primary goal of the 1.6.x series is to round out our 1.9 support by fixing any reported incompatibilities. Of course, as with any JRuby release, we will continue fixing any found incompatibilities and also improve performance. All users of 1.6.7.2 (and lower) are encouraged to upgrade to 1.6.8.

This release is a somewhat special release in that JRuby community members were primarily responsible for performing the backporting of fixes. These fixes represented what current users of JRuby 1.6.x wanted in a JRuby 1.6.8. Special thanks to merge-master David Kellum for putting so much effort into make JRuby 1.6.8 a reality.

Notable Changes:

Updated to RubyGems 1.8.24
Fixed a resource leak in LoadService
No more accidental GC of runtime state in unusual situations
Various 1.9 compability fixes

The JRuby community is pleased to announce the release of JRuby 1.7.0.preview2.

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

This is the second preview release of JRuby 1.7. The JRuby 1.7 release series represents a tremendous amount of work by dozens of contributors, and there are improvements in every subsystem. Users of highly-concurrent applications will see improvements in throughput and raw parallelism. And we have upped our compatibility level to match Ruby 1.9.3.

We have opted for another preview cycle due to the amount of reports about improperly working transcoding support. We have greatly improved transcoding of IO and users should be much happier with 1.7.0.preview2.

Due to some issues with Java 7’s invokedynamic support we decided to disable the support by default. It will be turned back on when Java 7 fixes those issues. See https://github.com/jruby/jruby/wiki/PerformanceTuning

Please, please, please test your applications against 1.7.0.preview2. We want to make 1.7.0 a rock solid release and your contribution is extremely helpful.

Notable Changes:

1.9.3 is now our default runtime mode (–1.8 is needed for 1.8.7 support)
Many 1.9.x compatibility fixes
invokedynamic has been disabled for now on Java 7 (still on by default on Java 8)
Performance and concurrency improvements
Java 5 support dropped (Java 6+ required)
Several IO transcoding issues
YAML now encodes scalars properly instead of using Java locale
Kernel#exec now does a true native exec on all platforms
Improvements and fixes to Java integration and embedding
Fix several native support issues on Solaris

The JRuby community is pleased to announce the release of JRuby 1.7.0.preview1.

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

This is the first preview release of JRuby 1.7. This release represents a tremendous amount of work by dozens of contributors, and there are improvements in every subsystem. Users on Java 7 should start to see gains from invokedynamic, the JVM’s new support for dynamic languages. Users of highly-concurrent applications will see improvements in throughput and raw parallelism. And we have upped our compatibility level to match Ruby 1.9.3.

We have opted for a preview cycle this time due to the significance of changes in this release and our desire to give users more time to test JRuby before releasing 1.7 final. When in doubt, file a bug…we’ll sort it out. We want to know issues users have with JRuby 1.7 sooner rather than later.

Notable Changes:

1.9.3 is now our default runtime mode (–1.8 is needed for 1.8.7 support)
Many 1.9.x compatibility fixes
Support for Java 7’s invokedynamic*
Performance and concurrency improvements
Java 5 support dropped (Java 6+ required)
Update to Rubygems 1.8.24
Update to Rake 0.9.2.2
259 issues resolved

*Note on invokedynamic performance:

Invokedynamic is still a new feature for the JVM, so we recommend running as recent a build of Java 7 as possible. Builds of OpenJDK/Oracle JDK prior to “update 2” will show poor performance.

Invokedynamic support can be disabled with -Xcompile.invokedynamic=false (passed to JRuby) for investigating perf issues or bugs.

The JRuby community is pleased to announce the release of JRuby 1.6.7.2.

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

This is a special release of JRuby which only updates our shipped copy of RubyGems to version 1.8.24. This version of RubyGems is the first version to verify that a RubyGems server certficate is valid. This helps to prevent a “man in the middle” style of attack when someone controls a portion of the network between you and the RubyGems server (See the release notes for RubyGems 1.8.23 and 1.8.24 for more details). All users are encouraged to upgrade to JRuby 1.6.7.2.

Note: You may also use the normal RubyGems upgrade mechanisms, but this will overwrite the Maven support we ship as part of JRuby.

Notable Change:

Update to Rubygems 1.8.24

The JRuby community is pleased to announce the release of JRuby 1.6.7.

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

The primary goal of the 1.6.x series is to round out our 1.9 support by fixing any reported incompatibilities. Of course, as with any JRuby release, we will continue fixing any found incompatibilities and also improve performance. All users of 1.6.6 (and lower) are encouraged to upgrade to 1.6.7.

Some astute readers of our release announcements will remember this snippet:

“Because master keeps getting further and further away from our 1.6 branch we have decided to make this our last 1.6 release. We largely fulfilled our goal of having reasonable 1.9 support.”

After releasing 1.6.6, we got a smallish flood of simple to fix 1.9 compatibility issues. We realized our charter of reasonable 1.9 support had not quite been reached. So we decided to put out 1.6.7. As of JRuby 1.6.7, we think we are leaving the 1.6 series at a nice stopping point. Plus, 1.7.0 is less than two months away.

Notable Changes:

Fix circular require issue in Rubygems introduced by our Maven gem support
Fix regression in popen* where streams get prematurely closed
Many 1.9-mode encoding bugs fixed in String, Regexp, StringIO, and YAML
Win32OLE now works in 1.9-mode
ffi on Win x64 now knows about basic types :size_t
Use jzlib to fix a set of issues with out zlib library
Reduced internal locking based on user reports
C extensions work on OS X again
Gems with gemspecs which contain UTF-8 multi-byte chars install in 1.9 mode

The JRuby community is pleased to announce the release of JRuby 1.6.5.1.

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

JRuby 1.6.5.1 is a special release with a single patch applied to our JRuby 1.6.5 source to correct CERT vulnerability CERT-2011-003. All users are recommended to upgrade to JRuby 1.6.5.1 to get this security fix.

A fuller JRuby 1.6.6 with bug fixes from the last two months will be released mid-January…

Background for the CERT advisory:

(for the impatient: predictable hashing algorithm and open access to a hash from a server can possibly allow Denial of Service (DOS) attacks)

Hashing 101

Hash tables apply a math function (hashing function) to the key of a key-value pair. The result of the hashing function is a location to a hash bucket which stores the key/value pair internally:

a[:heh] = 1
hashing_function(:heh) -> store :heh/1 in hash bucket #3
a[:foo] = 2
hashing_function(:foo) -> store :foo/2 in hash bucket #13
a[:bar] = 3
hashing_function(:bar) -> store :bar/3 in hash bucket #1

Hashes have many buckets and in theory all key/value pairs added to a hash will get spread out evenly across the hashes buckets. In practice, some number of keys will end up hashing into the same hash bucket (known as a hashing collision). As you get more key/value pairs stored to the same hash bucket the time to access those particular key/value pairs will slow down. This is because you need to walk some portion of the entries in the bucket to find the specific one you are looking for (hash structures will often make entries in an individual bucket a simple list structure).

a[:gar] = 4
hashing_function(:gar) -> store gar/4 in hash bucket #3 (same bucket as :heh)

In this example, accessing a[:gar] and a[:heh] may take longer than the other keys because they are sharing a hash bucket.

The Attack

The general application of the attack is for “the bad guys” to figure out a large set of values which will hash to the same hash bucket. Once they create this list they will send all those values to a server. The server will store them in a hash (think parameter list in Rack, for example). The act of storing or accessing any of those values takes longer and longer as the number of entries in a single hash bucket grows. The result will be a Denial Of Service (DOS) attack if enough values get stored.

hashing_function(:hostname) -> hash bucket #3
hashing_function(:aZ1) -> hash bucket #3
hashing_function(:cvg) -> hash bucket #3
hashing_function(:azr) -> hash bucket #3
... # many elided
hashing_function(:1fr) -> hash bucket #3
hashing_function(:yu3) -> hash bucket #3
hashing_function(:hyX) -> hash bucket #3

host = params[:hostname] # Uh oh! need to find this amongst many bucket buddies

The Fix

Adding a little bit of randomization to the hashing algorithm ends up making it much, much more difficult to figure out how to generate this type of attack. JRuby 1.6.5.1 (and all later JRuby releases) all have this additional randomization built into the hashing algorithm. The result should be decent hash bucket distribution that is difficult for attackers to predict. More information

This vulnerability is not exclusively an issue of JRuby. Other Ruby implementations also have a similar issue (also patched today). In fact, Java and PHP also appear to be susceptible to this style of attack. For more information, please see the CERT announcement.

Also, consider that language implementations are really only susceptible to this attack via frameworks which allow an external hacker to store arbitrary and/or unbounded key/values into a hash. Ruby Rack had this vulnerability, but they have fixed things so that the amount of parameters stored is bounded by a size to remove the possibility of a DOS attack. Rack users should upgrade to the latest version.

This release integrates experimental support for C extensions based on Ruby’s C API. And as with all major releases, we have improved stability and performance across the board in response to real-world user input.

Over the next month or two we plan on putting out quicker point releases in anticipation that 1.6.0 will get a new wave of feedback. Give JRuby 1.6.0 a try and let us know how things go.

Major Features:

Ruby 1.9.2 language and API compatibility
- Not implemented Encoding::Converter, ripper
Improved Ruby call performance
Built-in profiler (–profile, –profile.graph)
RSpec no longer bundled
C Extension support (experimental)
RubyGems Maven support (preview)
Improved compatibility and user experience on Windows

New readable backtrace format
Easier to embed in OSGi environment
Fixed regression which slowed down jar-based requires

We encourage Ruby and JRuby users alike to test out 1.6.0.RC2 to help us shake out remaining issues. It would be especially helpful if users would test out 1.9 mode (by passing –1.9 flag) to help us round out our 1.9.2 compatibility before the final 1.6.0 release.

Large number of 1.9 compatibility issues addressed
- Encoding issues (especially involving Regexp)
- Fiddle implementation

Compiler handles all 1.9 syntax now
Fixes for new backtrace accuracy, reliability
Removed all GPL or LGPL-only dependencies
Updated to RubyGems 1.5.0
C extension support prebuilt for OS X, Linux (32/64), Windows (32)

The JRuby community is pleased to announce the release of JRuby 1.6.0.RC1.

JRuby 1.6.0.RC1 is the first release candidate of JRuby 1.6.0.

JRuby 1.6.0 is the largest release of JRuby to date. This release fixes hundreds of user issues and brings compatibility with Ruby 1.9.2 to a very high level. We have made Windows a primary supported platform by adding it as a continuous integration platform, and JRuby 1.6 will provide Windows-based Ruby users with the best experience yet. This release integrates experimental support for C extensions based on Ruby’s C API. And as with all major releases, we have improved stability and performance across the board in response to real-world user input.

We encourage Ruby and JRuby users alike to test out 1.6.0.RC1 to help us shake out remaining issues. It would be especially helpful if users would test out 1.9 mode (by passing –1.9 flag) to help us round out our 1.9.2 compatibility before the final 1.6.0 release.

Major Features:

Ruby 1.9.2 language and API compatibility
- Not implemented Encoding::Converter, non-ASCII identifiers, ripper, fiddle
Improved Ruby call performance
Built-in profiler (–profile, –profile.graph)
RubyGems 1.4.2
RSpec no longer bundled
C Extension support (experimental)
RubyGems Maven support (preview)
Improved compatibility and user experience on Windows
jruby-complete.jar now includes 1.9 standard library
Embedding API refinements
Over 2000 commits and 265 issues resolved.

The JRuby community is pleased to announce the release of JRuby 1.5.6.

JRuby 1.5.6 is a minor follow-up release to address problems with mirroring of 1.5.5 in maven, update to 1.0.3 of jruby native launcher, and a few undesirable issues in windows. All users of JRuby 1.5.5 (and lower) are recommended to upgrade to 1.5.6.

1.5.6 Issues Resolved:

JRUBY-4352 Rbconfig’s Config::CONFIG provides wrong name for Windows 2008 Server, based on input from Rakesh Arora. (See 07fb757.)

JRUBY-5127 become_java! doesn’t add Ruby class methods as statics on the resulting Java class
JRUBY-5223 Marshal.load fails when Kernel.read is defined

Not in our tracking system:

ant.bat should be specified on Windows

The JRuby community is pleased to announce the release of JRuby 1.5.5.

(Note: Due to a showstopper bug found after the release jruby-jars gem and the inability to remove gem releases from rubygems.org we have skipped from 1.5.3 to 1.5.5. The 1.5.5 release is the same release that would have been 1.5.4 had we been able to re-release jruby-jars.)

JRuby 1.5.5 is a minor follow-up release to address problems executing some commands on Windows, a couple of Marshalling discrepancies with MRI, and a few other random production-affecting issues. We also improved the output and accuracy of –profile (try it out). All users of JRuby 1.5.3 are recommended to upgrade to 1.5.5.

1.5.5 Issues Resolved:

JRUBY-4766 Updated jaffl for YourKit compatibility
JRUBY-4865 Ant.load_from_ant is broken on Windows
JRUBY-4940 Cucumber Japanese example raises exception on JRuby

JRuby 1.5.3 is a minor follow-up release to address a thread deadlock, a spurious error involving selectors on windows, and a couple of fixes affecting bundler exec (and generally improves our exec() behavior). We also fixed a few highly specialized issues which should have no affect on most users. All users of JRuby 1.5.2 are recommended to upgrade to 1.5.3.

1.5.3 Issues Resolved:

JRUBY-5093 ConditionVariable use causes thread deadlocks
JRUBY-5076 SelectorProvider.openSelector() will sometimes fail on Windows

This development cycle has been our longest cycle yet (nearly 5 months), but it also has the most fixes. It also includes many new notable features (see below). Most of our bug fixes have been more of what we consider fine-tuning, since we keep getting into smaller corner-cases of compatibility for individual Ruby methods. In that sense, we expect if you had a good experience with JRuby 1.4.0 then 1.5.0 will be a no-brainer upgrade. If you haven’t tried JRuby in a while with your application, then please give us another try. Odds are whatever issue you were having before no longer exists!

1.5.0 Highlights:

New native access framework designed for performance and better FFI support
Native launcher for *NIX platforms
Ant support and Rake-Ant integration
Better and better support for Windows
Multiple performance improvements for Ruby-to-Java calling, improving correctness, memory, and speed.
Embedding API improvements based on user input (JSR-223, BSF, RedBridge, etc)
Software updates: Ruby 1.8.7 standard library update, RubyGems 1.3.6, RSpec 1.3.0
ruby-debug installed by default
Many fixes for Rails 3
Various improvements to startup time
Improved performance for Object#object_id/__id__
Reduced memory use for Java class metadata and faster loading of Java classes
jar-in-jar support in the classloader
The “open4” library now works properly

Misc

JRUBY-4574      jruby-openssl deprecation warning cleanup
JRUBY-4591      jruby-1.4 support

Today we’re releasing JRuby 1.4.1 as a recommended upgrade for all previous versions of JRuby. Previous versions contained a bug in JRuby’s regular expression engine that could allow an attacker to perform, for example, an XSS attack on a web application running under JRuby.

Download the 1.4.1 release.

This vulnerability fix is the only change from the previous JRuby release (1.4.0). Also note that the JRuby 1.5.0 release contains this fix as well.

Common Vulnerabilities and Exposures

The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2010-1330 to this issue. This is a candidate for inclusion in the CVE list, which standardizes names for security problems.

Impact

Any Ruby application code that uses regular expressions for string matching and substitution running under JRuby and using $KCODE = 'u' is vulnerable.

If a string contains invalid UTF-8 byte sequences in the (inclusive) range \xC0 to \xFD, the immediately following character will not be matched by a regular expression. Consider the following code:

str = "\xF6<script>"

$KCODE = ''
puts "KCODE: " + $KCODE
puts str.gsub(/</, "&lt;")

$KCODE = 'u'
puts "KCODE: " + $KCODE
puts str.gsub(/</, "&lt;")

Ruby 1.8.7 ignores the invalid bytes and continues, while Ruby 1.9.2 raises an ArgumentError due to the invalid bytes. But for JRuby, the effect is to fail to match the character following the invalid byte. For the example above example run with JRuby 1.4.0 prints the following. Note that the fourth line should be the same as the second.

KCODE: NONE
?&lt;script>
KCODE: UTF8
?<script>

The effect of this bug is magnified considering that the Rails html_escape or h helper essentially does what the above example does, meaning that any Rails view using the standard ERb escape helper method is vulnerable.

Releases

The JRuby 1.4.1 and 1.5.0 releases (including release candidates) all have the vulnerability fixed.

The fix was applied to the jcodings library which JRuby uses. As such, a source patch against the JRuby source is not available. Replacing the build_lib/jcodings.jar file in your JRuby source build with the jcodings version 1.0.3 jar file is sufficient to resolve the issue.

If you are unable to upgrade to JRuby 1.4.1, please contact the JRuby team at security@jruby.org for assistance.

Workarounds

Turn off $KCODE = 'u' in your application if you can. Otherwise, the only approach is to patch application or framework code to be aware of the invalid byte sequences.

Thanks

Many thanks to Jörn Hartmann (joern dot hartmann at gmail dot com) for finding and reporting the issue.

This development cycle has been our longest cycle yet (nearly 5 months), but it also has the most fixes. It also includes many new notable features (see below). Most of our bug fixes have been more of what we consider fine-tuning, since we keep getting into smaller corner-cases of compatibility for individual Ruby methods. In that sense, we expect if you had a good experience with JRuby 1.4.0 then 1.5.0.RC1 will be a no-brainer upgrade. If you haven’t tried JRuby in a while with your application, then please give us another try. Odds are whatever issue you were having before no longer exists! And we would really like help making sure JRuby 1.5.0 final is a solid release…so please try and report back with any problems.

1.5.0.RC1 Highlights:

Over 1250 commits since JRuby 1.4

We always appreciate community contributions. This cycle we’ve had more help than ever: David Calavera, Stephen Bannasch, Daniel Luz, Ian Dees, Koichiro Ohba, Hongli Lai, Hiroshi Nakamura, Colin Jones, Takeru Sasaki, Roger Pack, Matjaz Gregoric, Joseph LaFata, Frederic Jean, Alex Coles, Lars Westergren

Come join us this weekend, January 9-12, for the first ever JRuby BugMash!

The JRuby project has been growing impressively quickly, with frequent releases and a constantly expanding community. There’s a hefty list of impressive users and companies, and the team has been touring the world, trying their best to make it out to everyone who wants to hear and learn about the project.

As with any growing code base though, there’s a need to keep things tidy; frequent releases and speedy development also mean bugs, and things that need fixing–and that’s where we turn to you!

The first ever official JRuby BugMash will take place this Saturday, January 9th through Tuesday, January 12th. The core team will spend the days prior to the BugMash highlighting the specific bugs that are most important–you’ll want to keep an eye out for the Intro section. Then, Saturday morning, it’s off to the races! As a small token of our appreciation, in addition to the wonderful satisfaction of having made a difference to the project, we’ll be sending each of the first 100 participants a limited edition JRubyConf Poster. There are some more ‘tokens of appreciation’ up our sleeves for the top contributors, but we’ll keep those secret for now.

The JRuby Core Team will be around on IRC channel #jruby throughout the BugMash to help folks get started and to answer questions. Be sure to stop in and say hello!

bug trail

JRuby created (red) vs. resolved (green) bugs over the past 120 days

A security problem involving peer certificate verification was found where failed verification silently did nothing, making affected applications vulnerable to attackers. Attackers could lead a client application to believe that a secure connection to a rogue SSL server is legitimate. Attackers could also penetrate client-validated SSL server applications with a dummy certificate.

Common Vulnerabilities and Exposures

The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2009-4123 to this issue. This is a candidate for inclusion in the CVE list, which standardizes names for security problems.

Impact

Your application would be vulnerable if you’re using the OpenSSL::SSL::VERIFY_PEER mode on an OpenSSL-enabled socket (client or server) and any version of jruby-openssl prior to 0.6. An example using client-side validated SSL with the ‘net/https’ library is shown below.

  require 'net/https'
  uri = URI.parse('https://www.amazon.com/')
  http = Net::HTTP.new(uri.host, uri.port)
  http.use_ssl = true
  http.verify_mode = OpenSSL::SSL::VERIFY_PEER

  # This code should raise OpenSSL::SSL::SSLError
  # because it's not the correct trust anchor for
  # www.amazon.com.
  http.ca_file = 'test/fixture/verisign_c3.pem'
  response = http.start do |s|
    s.get(uri.request_uri)
  end

  # This code must fail as well because of an incorrect
  # trust anchor setting (no certs is the directory).
  http.ca_path = '/tmp'
  response = http.start do |s|
    s.get(uri.request_uri)
  end

  # verisign.pem is the correct trust anchor for www.amazon.com.
  # Only this request should be successful.
  http.ca_file = 'test/fixture/verisign.pem'
  response = http.start do |s|
    s.get(uri.request_uri)
  end

Release and Patch

The 0.6 release has the fix for the certificate validation vulnerability. Install the upgrade in the usual fashion by running jruby -S gem install jruby-openssl and ensuring that you get version 0.6 or greater.
A patch is available which should apply cleanly to the jruby-openssl 0.5.2 source. Ensure the code builds cleanly and passes tests by running jruby -S rake clean default.
Please contact security@jruby.org if you are unable to upgrade or use the 0.5.2 patch and require a backport. Let us know what version of jruby-openssl you’re using and help us understand how you’re using the library so we can determine whether you’re affected by the vulnerability.

Workarounds

No known workarounds exist, other than rewriting application code to use a different library to establish validated SSL connections.

Thanks

Thanks to NaHi (NAKAMURA Hiroshi - nahi at ruby-lang.org) for finding the problem and providing the fix.

The JRuby community is pleased to announce the release of JRuby 1.4.0

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

After three very helpful release candidates we have a final 1.4.0 release. This release ends a long release cycle in which we resolved a huge number of issues. The headline feature is a move to Ruby 1.8.7 support, in line with Rails’ own plans to make 1.8.7 the required minimum version of Ruby.

We have also gotten more serious about out 1.9 support (–1.9). The bigger applications mostly just work at this point, but we still have a ways to go on 1.9 support. Please try your 1.9 code in JRuby and help us firm things up.

1.4.0 Highlights:

JRuby is now compatible with 1.8.7 patchlevel 174
Windows Native Launcher
- Solves many reported bugs with our old .bat scripts
New YAML parser Yecht (bug-for-bug compatible with Syck!)
Improved Java Integration Support
- faster
- new java_method, java_send, and java_alias methods
Windows installer
New embedding framework
- Java 6 scripting out of the box
- New org.jruby.embed package to supersede JavaEmbedUtils
Many 1.9 mode (–1.9) fixes
- updated stdlib to 1.9.2preview2
- Rubygems now working
- Rails 2.3.3 simple apps working (2.3.4 has 1.9 bug)
rubygems 1.3.5
Much better error reporting
- shorter backtraces with less Java
- Ruby-compatiable syntax error reporting
307 bugs fixed since 1.3.1

We want to thank all the users who have been helping us to get a better release out. Special thanks to Hiro Asari, David Calavera, and Roger Pack for their recent activity in the project. We also want to welcome Yoko Harada as a committer to the project. Her work and support of our embedding efforts has been great.

The JRuby community is pleased to announce the release of JRuby 1.4.0RC3

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

Third time is a charm! Actually, this third release candidate is largely for the benefit of our Windows users. We have gotten reports of issues with our new installer and our new native launcher and we have been trying to make sure JRuby on Windows is a pleasant experience. We also fixed a Socket regression which had caused celerity to break.

The JRuby 1.4.0 release ends a long release cycle in which we resolved a huge number of issues. The headline feature is a move to Ruby 1.8.7 support, in line with Rails’ own plans to make 1.8.7 the required minimum version of Ruby.

We have also gotten more serious about out 1.9 support (–1.9). The bigger applications mostly just work at this point, but we still have a ways to go on 1.9 support. Please try your 1.9 code in JRuby and help us firm things up.

Please try your apps against 1.4.0RC3 ASAP and report problems

1.4.0RC1-RC3 Highlights:

JRuby is now compatible with 1.8.7 patchlevel 174
Windows Native Launcher
- Solves many reported bugs with our old .bat scripts
New YAML parser Yecht (bug-for-bug compatible with Syck!)
Improved Java Integration Support
- faster
- new java_method, java_send, and java_alias methods
Windows installer
New embedding framework
- Java 6 scripting out of the box
- New org.jruby.embed package to replace JavaEmbedUtils
Many 1.9 mode (–1.9) fixes
- updated stdlib to 1.9.2preview2
- Rubygems now working
- Rails 2.3.3 simple apps working (2.3.4 has 1.9 bug)
rubygems 1.3.5
Much better error reporting
- shorter backtraces with less Java
- Ruby-compatiable syntax error reporting
241 bugs fixed since 1.3.1

The JRuby community is pleased to announce the release of JRuby 1.4.0RC2.

Homepage: https://www.jruby.org/
Download: https://www.jruby.org/download

The JRuby 1.4.0 release ends a long release cycle in which we resolved a huge number of issues. The headline feature is a move to Ruby 1.8.7 support, in line with Rails’ own plans to make 1.8.7 the required minimum version of Ruby.

We have also gotten more serious about out 1.9 support (–1.9). The bigger applications mostly just work at this point, but we still have a ways to go on 1.9 support. Please try your 1.9 code in JRuby and help us firm things up.

Due to the overwhelming feedback we got from RC1, we have fixed a number of reported issues (shown below) for RC2. We expect that this will be our last RC before 1.4.0 final.

Please try your apps against 1.4.0RC2 ASAP and report problems.

1.4.0RC2 Highlights:

Windows Native Launcher
- Solves many reported bugs with our old .bat scripts

1.4.0RC1 Highlights:

JRuby is now compatible with 1.8.7 patchlevel 174
New YAML parser Yecht (bug-for-bug compatible with Syck!)
Improved Java Integration Support
- faster
- new java_method and java_send methods
Windows installer
New embedding framework
- Java 6 scripting out of the box
- New org.jruby.embed package to replace JavaEmbedUtils
Many 1.9 mode (–1.9) fixes
- updated stdlib to 1.9.2preview2
- Rubygems now working
- Rails 2.3.3 simple apps working (2.3.4 has 1.9 bug)
rubygems 1.3.5
Much better error reporting
- shorter backtraces with less Java
- Ruby-compatiable syntax error reporting
232 bugs fixed since 1.3.1

We want to give a couple of special acknowledgements for some contributors who went the extra mile this release cycle.

David Calavera has done a great job wrestling with Rubyspec failures and coming up with patches.

Yoko Harada has totally revamped our embedding APIs and created a new API called Red Bridge. This should address all of the reported embedding issues.

Download: http://dist.codehaus.org/jruby/

The fixes in this release are primarily obvious compatibility problems and performance enhancements. Our goal is to put out point releases more frequently for the next several months (about 3-4 weeks a release). We want a more rapid release cycle to better address issues brought up by users of JRuby.

Highlights:

Fixes so that JRuby runs in restricted environments better like GAE/J
Accessing primitive Java arrays are about 10x faster
timeout.rb is now ~40% faster
Method cache performance improvements
irb works in –1.9 mode now
- Additional Miscellaneous 1.9 fixes
rubygems 1.3.3, rake 0.8.7, and rspec 1.2.6 upgrades
66 bugs fixed since 1.2.0
