Aidan Skinner resolved QPID-1482.
---------------------------------
Resolution: Fixed
> Management Console cant complete PLAIN user authentication process
> ------------------------------------------------------------------
>
> Key: QPID-1482
> URL: https://issues.apache.org/jira/browse/QPID-1482
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker, Java Management : JMX Console
> Affects Versions: M4
> Reporter: Robert Gemmell
> Assignee: Aidan Skinner
> Attachments: QPID-1482_22nov2008.patch
>
>
> When the patches I supplied for QPID-1481 and QPID-794 are used, the
> management console is able to communicate with the broker across the
> JMXMPConnector link but is still unable to successfully complete the
> connection, however the failure now occurs during the PLAIN authentication
> process as opposed to before it like previously. Despite this, the management
> console reports that "Qpid server is not running."
> Enabling debug console output for the management console yields the following
> exception listing:
> java.io.IOException: java.lang.NullPointerException
