      Description

      When connecting a mqtt-client to wildfly-10.1.0.Final (which has artemis-1.1.0), I hit a nullpointerexception.

      I filedd this issue in the wildfly-jira: https://issues.jboss.org/browse/WFLY-9372
      At the suggestion of the wildfly-forum I bring this to your attention too by filing it here as well: It is not clear if the problem originates in artemis, or in the integration of artemis in wildfly, or both.

      see also http://activemq.2283324.n4.nabble.com/wildfly-10-1-0-Final-integration-for-MQTT-not-working-td4730581.html

      The stacktrace looks a lot like the issue reported in https://issues.jboss.org/browse/ENTMQBR-728

      The steps to reproduce are described in https://issues.jboss.org/browse/WFLY-9372
