JRuby 1.1.4 Released

The JRuby community is pleased to announce the release of JRuby 1.1.4!

JRuby 1.1.4 is the fourth point release of JRuby 1.1.  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:

- Massive refactoring of Java integration layer
  - 2-20x speed up of most features (calls, construction, arrays)
  - Many long-standing Ruby/Java interaction bugs fixed
  - Existing features made more consistent, reliable
  - Closures can be passed as interface to static methods, constructors
  - Java exceptions can be raised/rescued directly from Ruby
  - Massive memory efficiency improvements (a lot less GC)
- Beginning of Ruby 1.9 support (enabled with --1.9 flag)
  - Native complex/rational
- Additional efficiency, performance work in the interpreter
- Memory leak under --manage repaired
- FFI subsystem for calling C libraries
  - syslog module from Rubinius is working and included
  - win32 API support started
- Thread pooling improved (at least one production user now)
- Array concurrent-access improvements
- 72 issues resolved since JRuby 1.1.3
