I noticed this in a testsuite server log for EAP, but looking at WF code the same thing could happen there. Basically QueueReadAttributeHandler assumes a QueueControl exists and throws an NPE if that assumption is wrong:

19:14:25,402 ERROR [org.jboss.as.controller.management-operation] (management-handler-thread - 4) JBAS014612: Operation ("read-attribute") failed - address: ([

IIRC this kind of thing has been fixed elsewhere???
