--------------------------------------
Assignee: Stefan Guggisberg
> ConcurrentModificationException in SessionItemStateManager when multiple
> updates happening
> ------------------------------------------------------------------------------------------
>
> Key: JCR-1848
> URL: https://issues.apache.org/jira/browse/JCR-1848
> Project: Jackrabbit Content Repository
> Issue Type: Bug
> Components: jackrabbit-core
> Affects Versions: core 1.4.6
> Reporter: Chris Wilkes
> Assignee: Stefan Guggisberg
> Attachments: NPEandCMETest.java
>
>
> I'll post a trimmed down version of how I can get this error to be thrown. I
> bring this up as the code in SessionItemStateManager explicitly checks for a
> ItemNotFoundException so it looks like there was some thought put in to what
> happens if the underlying data changes.
