> The method clearPropertyDirect() in AbstractConfiguration has an empty implementation body. It is documented as "should be overwritten" but is not marked abstract.
> It should be abstract to prevent errors when subclassing AbstractConfiguration and using the clear() method where (indirectly) clearPropertyDirect() is being called.
> See addPropertyDirect() for comparison, which is abstract.
