I am trying to understand how the partition name is applied to the cluster. My 
initital impression was that two JBoss instances with two different partition 
names would treat each other are completely irrelevant, but this doesn't seem 
to be the case.

My configuration currently has 4 JGroups configurations in the MBeans for...

* org.jboss.ha.framework.server.ClusterPartition
* org.jboss.cache.TreeCache (TomcatClusteringCache)
* org.jboss.ejb3.cache.tree.PassivationTreeCache (EJB3SFSBClusteredCache)
* org.jboss.cache.TreeCache (EJB3EntityTreeCache)

Of these, only the first has any mention of the partition name. The rest will 
quite happily chat with all other servers listening on the same mcast_port 
regardless of the configured partition name. Is this the expected behaviour?

As I have found the other JGroups configurations (for HTTP sessions, SFSB  and 
Entities), I am starting to wonder what the ClusterPartition is actually used 
for. Seems the other groups have most of the actual functionality covered. 

I guess my question is whether the partition name is supposed to be applied to 
all of the JGroups (so it can be a true partition) or whether this is by design.

Thanks
