----------------------------------------
When I try the same thing on Wildlfy-11.0.0.CR1, I hit a similar error. Not a nullpointer,
but it is thrown at the same time: when connecting with an MQTT-client

for more info, see https://developer.jboss.org/message/976007
Reproducing in straightforward, see 'steps to reproduce'.
I'm not sure if this is related to the integration of artemis into wildfly, or to the
artemis server itself.
