> 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.
