JGroups protocol properties are not applied

      Modify standalone-ha.xml as follows:

      1. Set the JGroups default stack to "tcp"
      2. Replace the MPING protocol with: 
        <protocol type="TCPPING">
    <property name="timeout">30000</property>
    <property name="initial_hosts">127.0.0.1[7600]</property>
    <property name="port_range">0</property>
    <property name="num_initial_members">1</property>
</protocol>
      3. Deploy a distributable app

      (This can also be reproduced on OpenShift using the WildFly 9 cartridge as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=1220300.)

      Protocol properties are never applied, the check for applying properties is done on the legacy resource that only registers operation tranformation on old the old property address.

      Original report:

      When the JGroups subsystem is configured to use TCPPING, the following error occurs when deploying a distributable app:
