JLS says [p. 167, 8.4.6.4 Inheriting Methods with the Same Signature]:

"It is possible for a class to inherit more than one method with the same signature.
Such a situation does not in itself cause a compile-time error.
There are then two possible cases:
  If one of the inherited methods is not abstract, then there are two subcases:
   ...
     Otherwise, the method that is not abstract is considered to override, and therefore
     to implement, all the other methods on behalf of the class that inherits it.
   ...
"

JLS says [p. 166, 8.4.6.3 Requirements in Overriding and Hiding]:
"...
If the overridden or hidden method is public, then the overriding or
hiding method must be public; otherwise, a compile-time error occurs.
..."

JDK 1.1 compiler does not produce the needed error message for the test below.
