I've been seeing the following stacktrace a few times for test failures, e.g.http://lightning.mw.lab.eng.bos.redhat.com/jenkins/job/as7-master-testsuite-ip6/3720/testReport/junit/org.jboss.as.test.manualmode.ejb.client.reconnect/EJBClientReconnectionTestCase/testReconnectionWithClientAPI/ and https://issues.jboss.org/browse/AS7-5467
