JRuby 0.8.3 released


JRuby is a project to provide a Java implementation of
the Ruby language and interpreter.

JRuby 0.8.3 has been released. This version fixes a
huge number of problems and boasts the following notables:

  • irb (jirb) works
  • included Java classes are dramatically faster to load
    and use. A two minute Swing example now loads in
    approximately 5 seconds.
  • binding works
  • every constant scoping issue we knew of has been fixed
  • interpreter redesign work improved stack depth and
    brings us closer to supporting continuations
  • serious concurrency error when Ruby instances are passed
    back out to Java has fixed. This was a must for
    servlet-based solutions.
  • adornment of Java classes with Ruby methods via
    ‘extend_proxy’ method

Thanks to all people on the project and mailing lists for
making JRuby a much better piece of software. Special props
out to Charles Nutter for working so hard this development

The next release is going to be targetted for the beginning
of May. We want one more release out before JavaOne. We
are getting close to having RubyGems and Ruby on Rails


Tom, you’re doing a great job!
I’m looking forward to seeing your presentation at JavaOne.
