18 years ago @glassfishrobot Commented binod said: Instead of using iterator, the cleanup code now uses an array to scan all the open sessions. It then closes all open sessions. So, the code should be okay now for thread safety. I will need some help to tes the WAS-ActiveMQ combination. Planning to send an e-mail to the folks who reported this.

The cleanup code in MC, when executed in WAS, seems to crash into a piece of code that is not really executed in Sun appserver. The code in question is not thread safe. Resulting exception trace is shown below.
