Absolutely. I've been messing in this area in the last week or so, noticed this and meant to open a JIRA.  Thanks!

Full solution needs to reflect the fact that there may be more than one partition on the same server with clustered EJBs deployed.  Thus there would need to be more than one cache, and the cache integration code would need to know how to pick the correct cache.

> For ejb3-entity-cache-service.xml and ejb3-clustered-sfsbcache-service.xml the ClusterName should include the partition name. Here is why:
> We have 3 test instances and the two production cluster nodes within the same subnet (VLAN). The test instances have unique partition names (TEST1, TEST2, TEST3) and the production nodes share a common partition name (PROD).  In the default configuration all five nodes would form a cluster for the entity and SFSB caches. This would severely disrupt data consistency! We have solved this by including the partition name in the cluster name in the cache MBeans:
>     <attribute name="ClusterName">EJB3-entity-cache-${jboss.partition.name:DefaultPartition}</attribute>
