Hibernate Validator 4.3.0 was responsible for memory saving not the property. > > If your using MAT, I would drill into the "outgoing" references from the > org.hibernate.internal.SessionFactoryImpl and produce more pictures of the > objects consuming the larger part of that memory. I already done it. But the problem is that if I make side by side comparison between memory dumps from JBoss 4 and JBoss 7 I don't see a big difference. :-( Only the size of SessionFactoryImpl differs. > > Also, it might be helpful for us to see your persistence.xml. No problem.
