Don't like Roo. As you said yourself, it's magic, and it's not a compliment.
You know how .Net has partial classes? Well, there's a reason Java doesn't have that. Splitting the same class into multiple files is ewwww.
Groovy, on the other hand, is mostly cool.
P.S.
You make that "tsk" sound way too often close to the mic, so it's sort of annoying.

Double checked locking you used is not a good idea.

'Ewwww' meaning what, exactly?
As someone who has been creating tools that generate .Net source code, partials are a tremendously useful feature, as the language designers anticipated. The fact that they don't exist in Java makes it much more difficult for me to add the same value in that language. I think it is a real shame that people still limit their way of thinking about the feature set that a modern language should have to a language (Java in this case) that has barely changed in the last half decade or more.
