Richard Achmatowicz commented on AS7-4540:
------------------------------------------
This issue affects the running of the AS7 testsuite in the QA lab, in which only one
distinct multicast address is available per node.
Exception thrown in JGroups subsystem when diagnostics address/port
and udp address/port are distinct
-----------------------------------------------------------------------------------------------------
Key: AS7-4540
URL:
https://issues.jboss.org/browse/AS7-4540
Project: Application Server 7
Issue Type: Bug
Components: Clustering
Affects Versions: 7.1.1.Final
Reporter: Richard Achmatowicz
Assignee: Bela Ban
When using JGroups as part of AS7 in the server configuration standalone-ha.xml, upon
start up, we receive the exception:
{noformat}

{noformat}
even when the address / port combination for udp and the address / port combination for
diagnostics are distinct:
{noformat}
<socket-binding-group name="standard-sockets"
default-interface="public"
port-offset="${jboss.socket.binding.port-offset:0}">
...
<socket-binding name="jgroups-diagnostics" port="0"
multicast-address="ff0e::1" multicast-port="7500"/>
<socket-binding name="jgroups-mping" port="0"
multicast-address="${jboss.default.multicast.address:ff0e::1}"
multicast-port="45700"/>
<socket-binding name="jgroups-tcp" port="7600"/>
<socket-binding name="jgroups-tcp-fd" port="57600"/>
<socket-binding name="jgroups-udp" port="55200"
multicast-address="${jboss.default.multicast.address:ff0e::1}"
multicast-port="45688"/>
<socket-binding name="jgroups-udp-fd" port="54200"/>
<socket-binding name="modcluster" port="0"
multicast-address="ff0e::1" multicast-port="23364"/>
...
</socket-binding-group>
{noformat}
The expected behaviour is that as long as the ports are distinct, we should be able to
use the same mcast address for both udp and diagnostics.
