AMQ Resource adapter us hung while graceful Jboss shutdown

Issue

• JBoss A-MQ resource adapter is configured in JBoss EAP 6 to communcate with remote JBoss A-MQ server. During greaceful shutdown we see that JBoss EAP server hangs. In the thread dumps we could see that one of AMQ RAR threads is stuck with following stack:

ServerService Thread Pool -- 102" prio=10 tid=0x00007fbc28167800 nid=0x7ed0 in Object.wait() [0x00007fbc682f6000]

• Jira AMQ-5038 is filed for the same, however it is fixed in ActiveMQ 5.10.
