Alex Rudyy resolved QPID-7699.
------------------------------
Resolution: Duplicate
I looked through the broker logs and it seems that the test failure was caused
by the client bug already fixed on trunk as part of QPID-7505.
The below is my analysis of the issue.
The test tries to recieve from empty queue to verify that there is no messages
there. As part of synchronous received a command MessageFlush was issued which
removed the credits on broker side. The JMS client sent MessageFlow to
restore credits immediately after MessageFlush but Broker handled it after
receiving message. As result, at the moment of message receiving the consumer
with highest priority did not have credits and message was sent to the consumer
with lower priority.
In order to reduce the noise from failing tests on 6.x branches I suggest to
port the changes made in QPID-7505 into both 6.0.x and 6.1.x branches
