Please, explain me how CGLIB proxies & implicit polymorphism can live together?

For example, let A be a superclass of B, when i try to load B instance with the help of session.load(A.class, someBInstanceUUID), i would receive just a CGLIB proxy, which one cannot be casted to B.

In my project I had to disable lazy loading for all classes ang joined-classes ;( This my I have no advantages of HIbernate 3.0 vs Hibernate 2.2.
