[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-6960) NullPointerException in PreCollectionRemove Listener
[
https://hibernate.onjira.com/browse/HHH-6960?page=com.atlassian.jira.plug...
]
Kevin Jordan commented on HHH-6960:
-----------------------------------
I don't have any Sets of any type in my classes. Any Collection I have is a List with
an ArrayList implementation. I do have quite a few @ManyToMany, so it's probably
related to that with some certain Collection types.
NullPointerException in PreCollectionRemove Listener
----------------------------------------------------
Key: HHH-6960
URL: https://hibernate.onjira.com/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
