[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-7265) ConcurrentModificationException in SynchronizationRegistryImpl.notifySynchronizationsAfterTransactionCompletion due to SynchronizationRegistryImpl.clearSynchronizations clearing SynchronizationRegistryImpl.synchronizations

Gail Badner commented on HHH-7265:
----------------------------------
I was also thinking that there should be a way delegate to the session owner
(EntityManager) to determine if the session can be auto-closed. IMO, this is a better
alternative than adding a "system" synchronization along with more assumptions
about when it gets executed wrt observers, actions, and "normal"
synchronizations.
Steve, I'm not sure how properties can be used to determine if the session should be
auto-closed when using PersistenceContextType.EXTENDED. Using
PersistenceContextType.EXTENDED, IIUC, the session should only be auto-closed after a
transaction if the EntityManager is closed, so it's not a simple property lookup. Am I
missing something here (very possible)?
There is a test in the pull request that illustrates this case:
TransactionJoiningTest.testCloseAfterCommit().
