[rules-users] Shouldn't inserted objects be finalized after session.dispose()?

Hi, I thought that inserted objects should be finalized by the GC once a statefulsession is dropped by session.dispose(). However, this is done only if I retract handles one by one (session.retract(it.next())) using the method session.iterateFactHandles() and then session.dispose(). Is it wrong to expect that the object should be dropped by the GC once the session is disposed? Thank you for your help. Kind regards, Sylvain.
