From the developer:
JRuby provides a complete set of core "builtin" classes and syntax for the Ruby language, as well as most of the Ruby Standard Libraries. The standard libraries are mostly Ruby's own complement of .rb files, but a few that depend on C language-based extensions have been reimplemented. Some are still missing, but we hope to implement as many as is feasible.
You may want to check out more software, such as KiXforms, wxPython unicode for Python or CodeSmith, which might be similar to JRuby.
