just saw this failure:

http://hudson.qa.jboss.com/hudson/job/JBM2-stress/lastBuild/testReport/org.jboss.messaging.tests.stress.remote/PingStressTest/testMultiThreadOpenAndCloses/

connectionManagerArray is set outside of the synchornized block, while it's (ClientSessionFactoryImpl.java:915) is inside a synchronized block.

I've tried to write a multi-thread test. and I didn't have any success. I will spend more time on it tomorrow.

Maybe connectionManagerArray and readOnly attributes should be volatile?
