Thanks for the response. It's interesting because when I run jconsole all I can see is one ReplicationHandler jmx mbean. It looks like it is defaulting to the first slice it finds on its path. Is there anyway to have multiple replication handlers or at least obtain replication on a per "slice"/"instance" via JMX like how you can see attributes for each "slice"/"instance" via each replication admin jsp page?
