JRuby is a pure Java implementation of the Ruby interpreter, being developed by the JRuby team.

JRuby is free software released under a dual LGPL/GPL license.

JRuby is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application.

Here are some key features of "JRuby":
Ruby 1.6.7 compatible interpreter. (Not all builtin classes are supported yet!)
Working towards full compatibility with Ruby 1.8.1.
Support for scripting Java classes and interfaces in JRuby.
Bean Scripting Framework (BSF) support.

What's New in This Release:
Overall performance is 50-60% faster than 0.9.0.
Improved Rails support.
A new syntax for including Java classes into Ruby.
A new interpreter design.
Refactoring of the method dispatch, code evaluation, and block dispatch code.
Parser performance enhancements.
Rewriting of Enumerable and StringScanner in Java.
New experimental syntax for implementing interfaces.
86 Jira issues have been resolved since 0.9.0.
