[jira] Resolved: (QPID-2931) nulling the MessageReference handle on
the Message during QueueEntry disposal can result in NPE
[ https://issues.apache.org/jira/browse/QPID-2931?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Marnie McCormack resolved QPID-2931.
------------------------------------
Resolution: Fixed
Review ok, but we'd possibly be better to fix the NPE handling in the affected areas. Leaving the message handle seems a little wrong, even if it does get scavenged later.

> Nulling the MessageReference handle on the Message during QueueEntry disposal can result in NPE in various places throughout the broker, when attempts from seperate areas of the broker to retrieve details that are held only in the Message overlap the reference update and encounter unexpected NPE's. The reference nulling should be removed until this can be accounted for. (It is no longer as necessary as it once was, thanks to more aggressive QueueEntry scavenging in the QueueEntryList)
