Gail Badner commented on HHH-3876:
----------------------------------

Mark, is the collection mapped as lazy? If so, my guess is that you cannot reproduce this issue by stepping through with a debugger because the debugger itself causes the lazy collection to be initialized when it displays the collection's contents.

If you are using Intellij, you can configure the debugger so this doesn't happen. See https://www.hibernate.org/438.html#A7 for more info.

> We've started to notice the following exceptions being triggered from Hibernate 3.5.0-SNAPSHOT (built locally), but only under certain circumstances (editing a specific user, whilst being logged into the application as a specific user).  After stepping through both our application and hibernate through the whole update/commit process being run, I can't find anything that would be causing this problem.
> During processing, I see calls to org.hibernate.engine.Collections#prepareCollectionForUpdate for CollectionEntry[smx3.schema.PartyRole.agreementsFrom#2006094] (and other elements in the same collection) which is listed in the trace below.
> The collection which triggers the exception isn't consistently the same one, but seems to be localized to 4-5 different collections, I've also noticed that if I single-stepping through the process, if sometimes completes fine, which may indicate some race conditions somewhere.
> As I'm not entirely sure why the exception is being thrown, I'm not sure if this is a problem with Hibernate, or something wrong in our application somewhere.  Is there anyway I can identify why a collection entry wouldn't have been processed (and what does "processed" actually mean?).
