JRuby 1.0.0RC3 Released!

The JRuby community is pleased to announce the release of JRuby

This will likely be our final release candidate before our 1.0 release.
People are
encouraged to try out this release to help us find any remaining show
stopper issues. We
have spent a lot of time over the last month squashing compatibility
bugs and we have
confidence that applications ‘will just work’ ™*. Please try your
applications and
libraries against JRuby and give us feedback.

In the last month we have had a record number of people come in and
provide a patch or
report a bug. Interest in JRuby has exploded since JavaOne and
RailsConf, and many
development groups are now testing and deploying JRuby and JRuby on
Rails apps in
production. This has really helped accelerate our progress and JRuby is
looking much
better because of it. A few honorable mentions go out to: Koichiro
Ohba, Daniel B.,
David Montag, Dr Nic Williams, and Jon Tirsen.

We also want to thank all the people who hang out on IRC,
triage/report/patch issues, and
communicate on our mailing lists. Their interest has really helped
shape JRuby into a
better implementation.

As we approach our 1.0 release, we encourage Ruby (and JRuby) community
members to
contribute to a few projects key to the success of alternative

  • The RubySpec Wiki (www.headius.com/rubyspec) has slowly been growing
    into a free,
    community-driven specification of Ruby. Many people have contributed
    articles, and several
    of those directly aided JRuby development. The more people contribute to
    the wiki–in any
    way–the more it will begin to form a complete specification for Ruby
    the language and
    Ruby the platform. Have you written RubySpec today?

  • Both the Rubinius and JRuby projects have been building out their
    testing suites, to the
    point that JRuby now runs more regression/compatibility tests than any
    other Ruby
    implementation and Rubinius has the largest collection of RSpec
    specifications for Ruby.
    We two projects have been coordinating and cooperating on these
    testing/spec suites, but
    they need your help! Check out the JRuby or Rubinius source code and dig
    into the tests…
    you’ll be helping both projects and the community at large. For more
    test suites, check
    out the RubyTests project on RubyForge, where it is hoped that all test
    suites will
    eventually reside, and the ruby_test project under the Shards project on

JRuby’s tests are at http://svn.codehaus.org/jruby/trunk/jruby in the
test dir.
Rubinius’s specs are at http://code.fallingsnow.net/svn/rubinius/trunk
in the spec dir.
RubyTests is at http://rubyforge.org/projects/rubytests
RubySpec is at http://www.headius.com/rubyspec
