    // "Task.m()LFoo;" is an overpass method (that throws an AME).  So, even

    // though it is inheriting the method from its super class C, and Task has

    // a different class Foo than C, no LinkageError exception should be thrown

    // because the loader constraint check that would cause the LinkageError

    // should not be done.
