Jukka Zitting reopened JCR-549:
-------------------------------
> TransientFileFactory may throw ConcurrentModificationException on shutdown
> --------------------------------------------------------------------------
>
> Key: JCR-549
> URL: https://issues.apache.org/jira/browse/JCR-549
> Project: Jackrabbit
> Issue Type: Bug
> Components: core
> Affects Versions: 0.9, 1.0, 1.0.1
> Environment: svn: 437594
> Reporter: Marcel Reutegger
> Assigned To: Stefan Guggisberg
> Priority: Minor
>
> When Jackrabbit is stopped the shutdown hook of the TransientFileFactory
> iterates over all tracked temp files and deletes them. At the same time the
> reaper thread may still remove file references from the list of tracked temp
> files. This may lead to a ConcurrentModificationException in the shutdown
> hook:
> java.util.ConcurrentModificationException
> at java.util.AbstractList$Itr.checkForComodification(Unknown Source)
> at java.util.AbstractList$Itr.next(Unknown Source)
> at
> org.apache.jackrabbit.util.TransientFileFactory$1.run(TransientFileFactory.java:86)
