Gail Badner commented on HHH-2937:
----------------------------------

Did you see a NullPointerException actually thrown, or did you just notice that the check was not being done?

If you did see a NullPointerException get thrown, then please attach a runnable test case (Java + mapping) and a complete stacktrace so we can track down why PersistentBag.equalsSnapshot() is being called when the snapshot is null, since this condition could be due to a bug.
