      When setting proxy-list attribute which is static apache host list in modcluster subsystem instread of using multicast advertise, proxy-list is ignored and MCMP INFO message does not send to 127.0.0.1:6666 as below:

      <subsystem xmlns="urn:jboss:domain:modcluster:5.0">
    <proxy name="default" advertise="false" advertise-socket="modcluster" listener="ajp" proxy-list="127.0.0.1:6666">
        <dynamic-load-provider>
            <load-metric type="cpu"/>
        </dynamic-load-provider>
    </proxy>
</subsystem>

      The proxy-list attribute is already deprecated since EAP7.0, but I don't think it's appropriate to ignore proxy-list.
