[Bug java/18787] New: If an abstract class implements an interface, but does not define some methods, also its NON-abstract subclasses compile without defining the method.

[ativoli at gmx dot net]

Given the follwoing interface and abstact classes:
------
I.java
------
interface I {
    void test();
}
-------------
Abstract.java
-------------
abstract class Abstract implements I {}

The following class should NOT compile, as it does not define test(). However,
it compiles fine.
----------------
NonAbstract.java
----------------
class NotAbstract extends Abstract {}

           Summary: If an abstract class implements an interface, but does
                    not define some methods, also its NON-abstract
                    subclasses compile without defining the method.
