Hmm. Thanks for the tip. I've been working on trying to graft Groovy 2.1 onto an old Java app. The static type annotations don't work with Java 1.5. You have to have at least Java 1.6. (I discovered today) So, if you have Java 1.5, you can really only use Groovy 1.x language features, as well. Otherwise, it turned out to be not so hard to start putting little Groovy seeds into a Java garden, which I'm not going to rewrite as Grails. Just being able to use closures with the Groovy Collection extensions is pretty useful.
