Martin Ritchie updated QPID-1813:
---------------------------------
Status: Ready To Review (was: In Progress)
> Use of No Local can result in NPE after persistent message recovery
> -------------------------------------------------------------------
>
> Key: QPID-1813
> URL: https://issues.apache.org/jira/browse/QPID-1813
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: M3, M4
> Reporter: Martin Ritchie
> Assignee: Martin Ritchie
> Fix For: 0.5
>
>
> Summary:
> Because we do not store or recover the messages session Identifier (client
> id) along with the message on recovery the AMQMessage._sessionIdentifer is
> never set so subsequent no_local subscribers from that queue will result in
> NullPointerException.
> Returning null rather than throwing the NPE in AMQMessage getPublisher* will
> result in no_local checks being skipped.
> This is ok as the JMS spec for no_local is bound to a TCP connection.. The
> _sessionIdentifier will only be null after the message has been recovered
> from the messageStore, therefore, the publishing TCP connection will have
> been lost.
