The performance is really bad when you have a longer
inheritance tree, because for example, for each
EJBFacadeEntity, it has to instantiate the
EntityFacade, the ClassifierFacade,
GeneralizableElementFacade (just added this) and the
ModelElementFacade (with the factory) (thats 4 objects
for just one!) And with the change I added to make
the context stuff work, this even gets larger! Any
ideas on better ways to handle this stuff?
