AMQ7 uses jgroups 3.6. But the jgroups configuration files in the `clustered-jgroups` example are `JGroups-2.8.xsd` as below. One of the jgroups experts in Japan points out that it is disproportionately old and it uses some deprecated setting such as <MEARGE2> and <FC>.

<config xmlns="urn:org:jgroups"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="urn:org:jgroups file:schema/JGroups-2.8.xsd">

Could you please replace it with a new version one?
I think almost AMQ7's jgroups users hope to use TCPPING instead of current FILE_PING because a reason of using jgroups instead of clustering with UDP is to want to use AMQ7 in a cloud platform that cannot use IP multicast/broadcast. I think replacing current FILE_PING with TCPPING should please our AMQ7 users.

FYI, EAP 7 use jgroups 3.6 same as AMQ 7. You may be able to refer to those examples(, although it is different schema).
