Getting java.lang.ClassCastException after calling XSiteAdmin.status()

Set up a 4 node cross-site cluster. Nodes a & b are in site1. Nodes c & d are in site2. I've attached a sample configuration. Start all 4 hosts. Stop a particular cluster on host 'a'. I used JMX jboss.datagrid-infinispan:type=Cache,name="sessions(repl_sync)",manager="clustered",component=Cache stop(). Call jboss.datagrid-infinispan:type=Cache,name="sessions(repl_sync)",manager="clustered",component=XSiteAdmin status() on host 'b'. Expected Result: Some message like site2 [ONLINE] or site2[MIXED, offline on nodes: [a] ] Actual Result: java.lang.ClassCastException: org.infinispan.remoting.responses.CacheNotFoundResponse cannot be cast to org.infinispan.remoting.responses.SuccessfulResponse Using JDG 7.1.2. Not sure which ISPN that is, or if this is still an issue in master.
