artemis hierachic topic and clustering

hwaastad
Hi,
I have a java artemis (2.3.0) consumer listening to a "my-topic.#"

if I listen and produce on the same artemis instance, It's working
fine.

However, moving the consumer to another instance in a static configured
cluster, the artmis receiving the messages:

12:01:18,873
WARN  [org.apache.activemq.artemis.core.protocol.mqtt.MQTTPublishManage
r] null: java.lang.StackOverflowError
        at
java.util.concurrent.ConcurrentHashMap.get(ConcurrentHashMap.java:936)
[rt.jar:1.8.0_131]
        at
org.apache.activemq.artemis.core.postoffice.impl.BindingsImpl.getNextBi
nding(BindingsImpl.java:321) [artemis-server-2.3.0.jar:2.3.0]


Can this be a configuration issue?

relevant config:
b1:
<cluster-connections>
         <cluster-connection name="my-cluster">
            <connector-ref>netty-connector</connector-ref>
            <retry-interval>500</retry-interval>
            <use-duplicate-detection>true</use-duplicate-detection>
            <message-load-balancing>ON_DEMAND</message-load-balancing>
            <max-hops>1</max-hops>
         </cluster-connection>
      </cluster-connections>

<address name="my-topic">
           <anycast>
             <queue name="my-topic"/>
           </anycast>
         </address>

b2:
<connectors>
         <connector name="netty-
connector">tcp://localhost:61617</connector>
         <connector name="b1-
connector">tcp://localhost:61616</connector>
       </connectors>
  <cluster-connections>
         <cluster-connection name="my-cluster">
            <connector-ref>netty-connector</connector-ref>
            <retry-interval>500</retry-interval>
            <use-duplicate-detection>true</use-duplicate-detection>
            <message-load-balancing>ON_DEMAND</message-load-balancing>
            <max-hops>1</max-hops>
            <static-connectors>
               <connector-ref>b1-connector</connector-ref>
            </static-connectors>
         </cluster-connection>
      </cluster-connections>

consumer on queue "my-topic.#"
client: mosquitto_pub -m hei -t my-topic.xxx -p 1883

This looks like a bug to me.  Do you have a test-case that I could use to
reproduce the issue?  If not, could you create one (potentially based on
the "clustered-static-discovery" example shipped with the broker)?
