JRuby 9000 released

If I committed to using jRuby instead of regular ruby, I would have that nagging fear that Oracle would go after all the other companies that build their product using Java APIs.

is it faster than MRI?

Course it is. JRuby has been faster then MRI for a long time. That does not mean I use it for production.

JRuby is a great idea.

It has one pitfall which consistently stops me from using it though : poor support with newer releases of Rails, usually due to the Active Record stack not working well with the AR JDBC adapter.

I know some work was being done on a JRuby version of the standard pg gem (without the need for JDBC) which would be fantastic if it was completed and working.

JRuby 9000 now uses native operations for much of IO and almost all of Process. This makes us the first POSIX-friendly JVM language. Did they achieved this via JNI?

The system is called JNR - Java Native Runtime - http://www.oracle.com/technetwork/java/jvmls2013nutter-20135.... It uses libffi, which I guess the final call is made to via JNI.
