JRuby 1.6.0 Released: Now with Ruby 1.9.2 Support
JRuby is pretty unique among non-reference language implementations in that it's often more performant, powerful, and stable than the standard Ruby implementations. It's been rock-solid for us recently, and integrates with Java surprisingly well.<p>I often think that the Ruby world would be a more productive place if the original implementation had leveraged the JVM.
