Using Wildfly 10.1 standalone-full-ha.xml with the included ActiveMQ Artemis 1.1.0. Enabled STOMP by adding this to the activemq config:
<acceptor name="stomp-acceptor" factory-class="org.apache.activemq.artemis.core.remoting.impl.netty.NettyAcceptorFactory">
<param name="protocols" value="STOMP"/>
<param name="port" value="${stomp.port:61613}"/>
</acceptor>
Deployed a sample spring websockets war based on https://spring.io/guides/gs/messaging-stomp-websocket/
I have this running on 2 separate servers which are able to form a cluster. I am able to connect to both servers and send messages across, however when I disconnect one of the websockets, the following exception is thrown on the other server:
16:49:02,377 ERROR [org.apache.activemq.artemis.core.server] (Thread-7 (ActiveMQ-client-global-threads-926891052)) AMQ224037: cluster connection Failed to handle message: java.lang.IllegalStateException: Cannot find binding for ffaa538e-77c3-11e7-ba4b-7b9cb7ee40e2b7e6493a-77c3-11e7-ba4b-7b9cb7ee40e2

I have also tested this with Wildfly 11 Alpha and the included ActiveMQ Artemis 1.5.3 but I get the same error every time I disconnect a websocket.
I also get the following errors when I shutdown a server, but I am less concerned about these since they only happen during shutdown:

Is it an issue with the spring websocket example?
Do I need to change something in the default standalone-full-ha.xml to get this to work properly across a cluster, without throwing exceptions on client disconnect?
The version of Artemis in Wildfly is a bit behind the latest upstream (1.5.3 vs 2.2.0). Have you tried this with a cluster of standalone Artemis 2.2.0 nodes?
