Groovy advantages over Jython or Jruby?

Question

Why would I choose to use Groovy when I could use Jython or Jruby? Does the language provide any inherent advantages to make up for the fact that Jython and Jruby skills are app

Answer 1

I've only had experience with Jython and Groovy. The biggest disadvantage with Jython, at the moment, is that the latest release recommended for production (2.2.1) has a feature set that "roughly corresponds to that of Python-2.2" (Jython FAQ). There is a beta implementing what I assume is Python 2.5, which is now a version behind. Don't know if the same can be said for JRuby.
