Contention on a mutex during a stress when using SimpleAuthenticationPlugin
---------------------------------------------------------------------------

                 Key: AMQ-3454
                 URL: https://issues.apache.org/jira/browse/AMQ-3454
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.5.0
            Reporter: William
            Priority: Critical
         Attachments: amq-dump


I am testing ActiveMQ 5.5 with my own stress test. I tried to implement a stress test that
use jms ressource in the same fashion that my application would do. 

For that, I used jms template (from Spring) and  a pooled connection factory (as recommended).
I run a fixed number of thread that plublish on fixed number of topics. Each thread pick up
a topic and enter a loop that will send a message on the choosen topic.

The issue is reproductible with SimpleAuthenticationPlugin active.  

Configuration of the test : 

* 100 topics
* more than one thread per topic (actually 1500 producer threads)

Common connection properties :
* alwaysSessionAsync=false
* dispatchAsync=false 
* optimizeAcknowledge=true
* socketBufferSize=131072&trace=true&wireFormat.cacheSize=2048&wireFormat.tcpNoDelayEnabled=true&wireFormat.tightEncodingEnabled=true&keepAlive=true&soTimeout=10000&connectionTimeout=10000\


Producers : 
* Message are not persistent
* There is no transaction
* Message expiration time is 30s
* Unsing JMS template singleton with a PooledConnectionFactory
* 3 JVM running 
* connection options alwaysSyncSend=true,copyMessageOnSend=false

Consumers :
* just listening to each topic with a SimpleMessageListenerContainer and count messages received
* 3 JVM running 


In attachment, you will find activemq config file and thread dumps. I can attach the producer/consumers
code if you need it but I think you have your own tests.

This Jira is critical for me because security is mandatory for our use.

If you need more information, please ask.
