JRuby 1.7.0.preview2 Released

Tuesday, August 07 2012

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

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 http://wiki.jruby.org/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
  • 122 issues resolved
