This problem is strictly a problem with the ANTLR grammar itself.
It doesn't recognize the generic type and does the wrong thing.
Too much a pain to integrate into the existing v2 grammar, so Ter  
postponed it.

The generated code (without generics) works fine with 1.5, though.
I'd use the workaround Johannes mentioned.
