Hi Steve,
I still have leaking connections when I have unidirectional one to many collection with orphan removal. Please run modified LazyLoadingTest test case to reproduce this situation.
log:
ERROR AssertionFailure:43 - HHH000099: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session): org.hibernate.AssertionFailure: collection owner not associated with session: org.hibernate.test.ondemandload.Store.inventories
WARN AbstractPersistentCollection:246 - Unable to close temporary session used to load lazy collection associated to no session
