Javac-ea (early access release, May 1999)

1. javac-ea says it is an error for an anonymous class to call a
protected method of the enclosing class' superclass.
(Anonymous classes have the same access rights as their
enclosing class, and should be able to call a protected method of
the enclosing class' superclass).

2. javac-ea runs into an internal error if the target qualifier is left off.
