[ANN] JRuby 1.7.0.preview1 released

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

- Homepage: http://www.jruby.org/
- Download: http://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痴 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値l
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痴 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 砥pdate 2will show poor performance.

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