> During the work on QPID-4164 it was found that JMX threads can spin in the Queue MBean if they fail when viewing message content, looping down into the message and back store asking for content which will never be returned. These threads will never stop spinning, and will consume CPU resources and introduce additional/unnecessary resource contention within the store layer.
> The view content method of the Queue MBean should be updated to avoid this possibility.
