Andreas, I have worked on several JRuby apps that are in production, and I would say that the best thing about JRuby is the ability to deploy a Rails/Rack app on "enterprisey" app servers. TorqueBox 2.x is my current favorite, which is a nice wrapper around JBoss 7. All the enterprise, none of the XML. Clustering is a breeze, and with InfiniSpan you get the equivalent of a distributed memcached for free, plus built-in message queueing and background jobs, etc.
There are certainly rough edges that will cut you, but if you use Rails you are used to that anyway. Both JRuby and TorqueBox have full-time, paid developers working every day on improving them. On the small chance you find a gem you cant use in JRuby, there is certainly a Java jar you can use instead. If you think Ruby has a robust gem ecosystem, wait until you see what Java has to offer. Bottom line is, come on in, the water's fine!
