Websphere MQ 126.96.36.199
I've followed instructions (http://www.ibm.com/developerworks/websphere/library/techarticles/0710_ritchie/0710_ritchie.html) to configure a jca connection to wsmq. It works with JBoss 4.2.2 but when using 5.1.0 it issues a ConcurrentModificationException when I try the demo application (WMQ_IVT). I've already applied Fix Pack 188.8.131.52 but it didn't solve the problem. Can anyone please help?
