Subject [jira] [Created] (AMQ-3299) Prioritizing of messages isn't fully applied to all messages during test.

Prioritizing of messages isn't fully applied to all messages during test.
-------------------------------------------------------------------------

                 Key: AMQ-3299
                 URL: https://issues.apache.org/jira/browse/AMQ-3299
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.4.2
         Environment: Operating System = Windows XP version 5.1 running on x86
Java; VM; Vendor = 1.6.0_23
Runtime = Java HotSpot(TM) Client VM 19.0-b09
            Reporter: Robert Liguori


Considering this link: http://activemq.apache.org/activemq-performance-module-users-manual.html
and sample test performance benchmarks of 1 million messages every 5 mins, I created and ran
a priority test with 333 messages begin sent every second.

Problem: It appears as if the priority algorithm is not being applied (or even attempted)
to many of the messages in the middle of the run.  Consider this output and examine the message
order, the number with the # signs are represent the message number sent by the producer,
these numbers are ordered meaning that the producer did not order them before sending them
out:

I will separately attach the full producer and consumer logs.  You will notice clear ordering
of messages at the beginning and end of the test.
