AnnotationBinder and HbmBinder improperly set EntityPersisterClass upon class hierarchy
---------------------------------------------------------------------------------------

                 Key: HHH-6724
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6724
             Project: Hibernate Core
          Issue Type: Bug
          Components: metamodel
    Affects Versions: 4.0.0.CR4
            Reporter: Emmanuel Bernard
            Assignee: Emmanuel Bernard
             Fix For: 4.0.0.next


In Hibernate Core 3.6, PersisterClassProvider (the father of PersisterClassResolver) was called before the Binder phase could set any default value (in particular in the inheritance case). This was done in EntityBinder.bindEntity() if @Persister was not explicitly set.

In Hibernate Core 4, such calls to PersisterClassResolver are done in PersisterFactoryImpl#createEntityPersister. This is after the Binder phase which sets persister values when mapping a class hierarchy (AnnotationBinder#bindClass line 608, 631 and 651).

Hibernate OGM is not given opportunity to override the value.

A fix for this involves not setting PersistentClass#setEntityPersisterClass in the Binders (unless explicitly set) and move the class hierarchy decision logic to PersisterClassResolver. Note that the initial PersisterClassResolver implementation was incomplete.
