Resolution

Make sure the jgroups subsystem has cluster="ejb" on the ee channel, this is the default value and should typically not be changed.

        <subsystem xmlns="urn:jboss:domain:jgroups:5.0">
            <channels default="ee">
                <channel name="ee" stack="udp" cluster="ejb"/>
            </channels>
