[ANN] JRuby 1.2.0RC2 Released

The JRuby community is pleased to announce the release of JRuby 1.2.0RC2

Homepage: http://www.jruby.org/
Download: http://dist.codehaus.org/jruby/

JRuby 1.2.0RC2 has fixed many many compatibility issues and continued to
improve general performance. Due to popular demand we have a new
system. 1.x.y was our old number system where x was the major release
and y
was the minor release. Our new system just chops off the vestigial ‘1.’
the front. 1.3, 1.4, …, 1.x will just be minor releases of our
major release.

Please try your apps against 1.2.0RC2 ASAP and report problems


  • Improved Ruby 1.9 support (via --1.9)
    • Compiler now works
    • Almost all of the missing 1.9 methods have been added
  • New experimental --fast flag which does more aggressive optimizations
  • Large scale compiler and runtime cleanup and performance audit
  • Parsing is 3-6x faster now.
  • Preliminary android support (Ruboto)
  • Rails pathname issue fixed on Windows
  • Major bug triage since last release
  • 1052 revisions since 1.1.6
  • 232 bugs fixed since 1.1.6

Bugs fixed since RC1
