Hi, to answer my own question: The meta-model is re-created whenever EntityManagerFactoryImpl is instantiated. Hence old meta-model elements will be GC'ed and with them the SessionFactoryImpl etc. (if it was closed).
In my case now there was a static reference from application code to one element from the meta-model, hindering that element and with it the factory to be GC'ed. -- Gunnar 2011/7/19 Gunnar Morling <gunnar.morl...@googlemail.com>: > 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.
