With AMQ 7.11 there is required change in configuration of acceptor needed for EAP 7/8 <-> AMQ 7.11 to work properly.

Issue is related to allowing to configure remote AMQ 7 broker using JMS messages sent to activemq.management queue which is used by EAP to create queues/topics on AMQ 7 broker. Following options should be added

supportAdvisory=false;suppressInternalManagementObjects=false

Like:

<acceptor name="artemis">tcp://0.0.0.0:61616?anycastPrefix=jms.queue.;multicastPrefix=jms.topic;...;supportAdvisory=false;suppressInternalManagementObjects=false</acceptor>

This change should go Configuring Messaging guide to EAP 7.4 and EAP 8.0
