[hibernate-dev] Static meta-model and references to SessionFactoryImpl

Hi, while analyzing a memory leak I noticed that instances of the static JPA 2 meta model seem to hold references to Hibernate's session factory. In my case the path to the factory is the following: SingularAttributeImpl#attributeType -> EmbeddableTypeImpl#hibernateType -> ComponentType#typeScope -> TypeScopeImpl#factory Since the members of the meta model are static I think that means that the factory won't be GC'ed although it was closed by the application, hence consuming memory otherwise not needed anymore. WDYT, is this an issue that should be addressed? Or are the meta model instances removed at some point of time? I don't know really much about Hibernate Core, so I hope my questions are not completely clueless ;-) Thanks, --Gunnar
