Description

When running the test case from OPENJPA-228 (after a few modifications to get it working), I get the exception included below. If I change the 'Article' mapped superclass to be named 'ArticleBase', things work.

It looks like this is happening because multiple classes are registering for the same alias. We should change the enhancer to not register aliases for mapped superclasses.
