GWT SuperDevMode only compiles changes (and its dependencies) but sometimes it might miss a change which can result in broken code. As you said the only workaround is to force a change to the affected method or clean SDM cache and rebuild the whole app (click the small clean button on the SDM UI at localhost:9876).--
Of course it is a bug but without being able to reproduce it, I guess it is tough to find and fix.
