I think I have the same problem as you. See my earlier post on this
forum:
https://groups.google.com/d/topic/google-web-toolkit/rdoCr79EQbE/discussion
I wanted to file an issue about this problem, but I couldn't track down the
exact behavior of the GWT compiler when this happens (except the info you
can see in my linked post). I didn't file an issue in the end because I
didn't have a deterministic way to reproduce it. If we would be able to
reliably reproduce the issue, that would be the first major step towards
fixing it. Also, for me, it happened with normal classes too, not just
anonymous classes. Also worth mentioning that I never had this problem with
the normal GWT compiler, only with SuperDevMode.
