Our company use JBoss EAP 7.0.4

The messaging subsystem in standalone-ha.xml which is being looked up with JNDI is such:

<subsystem xmlns="urn:jboss:domain:messaging-activemq:1.0">

  <server name="default" id-cache-size="30000" async-connection-execution-enabled="true">

    ...

    <remote-connector name="netty" socket-binding="messaging-remote"/>
    <remote-acceptor name="netty" socket-binding="messaging"/>

        <connection-factory name="RemoteConnectionFactory" reconnect-attempts="10" retry-interval-multiplier="1.0" retry-interval="1000" block-on-acknowledge="true" client-failure-check-period="20000" ha="true" entries="java:jboss/exported/jms/RemoteConnectionFactory" connectors="netty"/>

    ...

  </server>
</subsystem>

The socket binding for "messaging" and "messaging-remote":

<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
...
  <socket-binding name="messaging" port="${messaging.connector.port:5445}"/>

  <socket-binding name="remoting" port="${jboss.remoting.port:4447}"/>

  <outbound-socket-binding name="messaging-remote">
    <remote-destination host="${remote.messaging.server.bind.address:127.0.0.1}" port="${messaging.connector.port:5445}"/>
  </outbound-socket-binding>
</socket-binding-group>

I set jboss.socket.binding.port-offset=100 for EAP server, and for JMS client try to lookup for "RemoteConnectionFactory" with the following properties (considering the offset):

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");

props.put(Context.PROVIDER_URL, "remote://localhost:4547");

InitialContext ctx = new InitialContext(props);

ConnectionFactory connectionFactory = (ConnectionFactory) ctx.lookup("jms/RemoteConnectionFactory");

Lookup succeeds, but creating session from connection factory fails with exception:

javax.jms.JMSRuntimeException: Failed to create session factory

...

Caused by: ActiveMQNotConnectedException[errorType=NOT_CONNECTED message=AMQ119007: Cannot connect to server(s). Tried with all available servers.]

The detail log reveals that ConnectionFactory receives destination info without port offset:

Session factory tries to use the default binding port 5445, though in fact the valid binding port with offset is 5545.

The only workaround to deal with it I found was:

a) to set fixed-port attribute:

<socket-binding name="messaging" port="${messaging.connector.port:5445}" fixed-port="true"/>

b) explicitly set messaging.connector.port property with offset 5545.

I suspect it is a bug in EAP. Please, fix.
