return type and generics

This compiles OK:

@TypeChecked
class C extends Script {

    @Override
    List<String> run() {
        [11, 12]
    }
}

however, in IDEA, with @TypeChecked, it's highlighted as an error. I didn't
really expect this to produce an error in static type checking, but I'm
just wondering if IDEA is going more here than @TypeChecked does.

Or is there some way to get type checking to flag this as an error?
cheers, jamie

Cheers Cedric: https://issues.apache.org/jira/browse/GROOVY-7598

Pretty minimal report but I think it has all it needs.

Yes, there's a way: please file a bug report :) It should have been caught.
I'm actually very surprised it doesn't :)
