Subject Re: Strange, intermittent problem running the new models.company tests

Kevin-

It could, but it would just be a spec compliance. OpenJPA does allow  
you to have final classes. The spec just prohibits it because one of  
the ways to implement support for property access is to dynamically  
generate a subclass to the entity (which isn't possible if the entity  
is final).
