Where does this dummy_operation_name and dummy_queue_name comes from?
Is that from some monitoring tool you are using?
Also what version of wildfly?
I replaced the real operation- and queue-names in the stacktrace with dummy values;
we use Wildfly version 10.1.0.Final
Have your read my last comment about the Wildfly version (10.1.0.Final)?
It's confusing to see "dummy_operation_name" in there. Can you tell us what exact operation name it is? It's fine if you don't post the queue name but the operation name isn't really application specific, to hide it.
