Fixed deadlocking behavior in actors.

Specialization removed a 'private' modifier on Actor.resumeActor. Mixin
did not mix this method in actor implementations, believing it was
private. At runtime, an AbstractMethodError was thrown, but swallowed by
forkjoin (probably), resulting in an apparent deadlock. It would have
been much faster to find and fix if the stacktrace was printed, as it is
in Java 1.5. No review.
