["pablo at freality dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This source file:
-- Test.java
interface A { void inheritedAbstractMethod(); }
interface B extends A {}
abstract class C implements B {}
abstract class D extends C {
  void problemMethod() {
    inheritedAbstractMethod(); // Should be in scope, but gcj doesn't find it.
  }
}
