getUnproxiedClass

public <T> Class<T> getUnproxiedClass(Class<?> klass)

Return the actual entity class registered with the persistence provider. This may be the same class or it may be different if the given class is is a proxy. For example, the entity class may be Person, but the class of the proxy may be Person_$$_javassist_5. We need to normalize this to Person so that we can create correct queries and inspect metadata correctly.
