-------------------------------------------------------------------

The VERSION method [1] was added via MODCLUSTER-409 but there is currently nothing else, the documentation/contract, versioning strategy, handling in Java does not exist.

The reponse looks like this:

{noformat}
[rhusar at syrah ~]$ curl -XVERSION http://127.0.0.1:9090 -H "Accept: text/xml"
<?xml version="1.0" standalone="yes" ?>
<version><release>mod_cluster/1.3.2.Alpha1-SNAPSHOT</release><protocol>0.2.1</protocol></version>
{noformat}
or
{noformat}
[rhusar at syrah ~]$ telnet ::1 9090
Trying ::1...
Connected to localhost.
Escape character is '^]'.
VERSION
release: mod_cluster/1.3.2.Alpha1-SNAPSHOT, protocol: 0.2.1
Connection closed by foreign host.
{noformat}


There is no mention of protocol version 0.2.1 even in the protocol page! https://developer.jboss.org/wiki/Mod-ClusterManagementProtocol
