Summary: ConcurrentModificationException in Queue model

Initial Comment:
Hi

I got this ConcurrentModificationException when loading
the Queue model of OpenJMS with large amount of small
messages in a stress test. This bug is just a reminder for
now since I cannot reproduce it and it is quite sporadic.

Regards
