>                 URL: https://issues.apache.org/jira/browse/QPID-5784
>             Project: Qpid
>          Issue Type: Bug
>          Components: Java Broker
>            Reporter: Keith Wall
>            Assignee: Keith Wall
>            Priority: Minor
>             Fix For: 0.29
>
>
> Since QPID-5410, if the Broker is shutdown whilst the coalescing commiter is still completing
jobs, there is an opportunity for a NPE from the commit thread.   This is being written to
stderr. 
> {noformat}
> Exception in thread "Commit-Thread-test" java.lang.NullPointerException
>         at org.apache.qpid.server.store.berkeleydb.CoalescingCommiter$CommitThread.processJobs(CoalescingCommiter.java:245)
>         at org.apache.qpid.server.store.berkeleydb.CoalescingCommiter$CommitThread.run(CoalescingCommiter.java:214)
> {noformat}
> This defect has no end-user impact, as inflight transactions will still be aborted.
> The code should be changed to avoid the NPE possibility.
