org.eclipse.persistence.internal.oxm.WeakObjectWrapper
INTENRAL:
Purpose: This class is used for caching objects based on Object Identity instead of a Primary Key. This class acts as the Primary Key, and wraps the domain object itself in a weak reference. hashCode and equals methods are implemented to insure identity is maintained.
