JRuby 1.1.3 is the third 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


  • RubyGems 1.2
  • Greatly improved interpreter performance
  • jrubyc compiler usability improvements and bug fixes
  • Reduced memory usage and object churn
  • Dozens of IO-related and core class RubySpec fixes + reduced memory
    for IO
  • ThreadGroup fixes to resolve Mongrel “dead thread” issues
  • New options/properties for tweaking JIT, thread pooling, and more
  • Block invocation performance improvements
  • Much faster Time performance
  • Much better support for --debug
  • 82 issues resolved since JRuby 1.1.2
