> 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.
