The JRuby community is pleased to announce the release of JRuby
1.7.0.RC2.
Homepage: http://www.jruby.org/

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 dont 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. http://wiki.jruby.org/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.
