JRuby 1.1.6 is the sixth 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


  • Additional Ruby 1.9 support (via --1.9)
    • Full 1.9 parser
    • Most core 1.9 methods/libraries/classes
  • An evergrowing list of dead IO references bug fixed
  • Much faster Array.sort
  • Run gems out of jar files without having to unpack them.
  • Store gem repositories in jars and load them via the classpath.
  • Improved JavaEmbedUtils for embedders
  • Removed two measurable memory leaks during RC process
  • 74 bugs fixed since 1.1.5
