Adam Warski commented on HHH-6960:
----------------------------------
@Marek I'm pretty sure the issue could be reproduced with several entities. Would it
be possible for you to try? Maybe the null check makes the NPE go away, but does the audit
work properly?
@Gail First we need a test case :)
NullPointerException in PreCollectionRemove Listener
----------------------------------------------------
Key: HHH-6960
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6960
Project: Hibernate ORM
Issue Type: Bug
Components: envers
Affects Versions: 4.0.0.Final
Environment: Hibernate 4.0.0 to MySQL
Reporter: Kevin Jordan
Assignee: Adam Warski
I'm getting a NullPointerException on line 47 of
EnversPreCollectionRemoveEventListenerImpl very consistently. I wasn't sure if it was
due to lazy collections or not, but it seems that it fails if they're eagerly fetched
or lazily fetched. I'm guessing it has something to do with getLoadedPersister()
returning a null value since the comments for it say "This is only available late
during the flush cycle". The stack trace is
