[ANN] JRuby 1.7.0.preview2 released

Ruby 1.7.0.preview2 Released
Tuesday, August 07 2012

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

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