Kestutis Gedminas updated AMQ-7154:
-----------------------------------
Description:
We get a deadlock on AMQ. After analysis, it looks like in case if expired
messages thread is processing DLQ queue at the same moment when poisonAck is
received we run into preexisting racing condition in code due to inconsistent
lock acquiring order.
