[ANN] JRuby 1.3.0RC1 Released

The JRuby community is pleased to announce the release of JRuby 1.3.0RC1

Homepage: http://www.jruby.org/

JRuby 1.3.0RC1 is a release to fix some issues which prevented JRuby
working with Google App Engine (GAE/J). We decided to put out a shorter
release so that users interested in GAE/J could get going without
needing to
build JRuby from scratch.

Please try your apps against 1.3.0RC1 ASAP and report problems


  • Fixes so that JRuby runs in restricted environments better like GAE/J
  • Accessing primitive Java arrays are about 10x faster
  • timeout.rb is now ~40% faster
  • irb works in --1.9 mode now
    • Additional Miscellaneous 1.9 fixes
  • rubygems 1.3.2 and rspec 1.2.6 upgrades
  • 22 bugs fixed since 1.2.0
