While defining "timeout" property in TCPPING as below generates WARN messages.

TCPPING configuration as per link [1] EAP 7 high availability configuration guide

~~~~~~~~
<protocol type="TCPPING">
<property name="initial_hosts">
${jboss.cluster.tcp.initial_hosts}
</property>
<property name="port_range">
0
</property>
<property name="timeout">
2000
</property>
</protocol>
~~~~~~~~

Below is the WARN message generated :

~~~~~~~~
WARN [org.jgroups.stack.Configurator] (MSC service thread 1-2) JGRP000014: Discovery.timeout has been deprecated: GMS.join_timeout should be used instead
~~~~~~~~

Resolution :

Remove "timeout" property from TCPPING and run the TCP cluster.

Using the above solutions were not generate the WARN messages.

We need to EDIT these changes in the EAP 7 high availability documentation.

Root Cause :

Discovery is a superclass of TCPPING hence the above WARN message is logged.
