Robbie Gemmell commented on QPID-4012:
--------------------------------------
I have made an update to change how the priorities are compared on queue
entries in order to avoid retrieving the message metadata, and thus avoid
trying to access it after it may have been removed from the store.
I have attached the patch, I expect it should apply to the 0.16 source as well
if you want to do that.
