Seems you've found a bug: http://jira.jboss.com/jira/browse/JBCACHE-1114. Unfortunately, there's no simple workaround. As for the javax.management.InstanceNotFoundException, there is a solution for that. From pt.iol.services.cache.CacheContext, don't call TreeCache.stop(). Call TreeCache.stopService(). Make equivalent changes for any call to create(), start() or destroy(). In JBC 1.x, create()/start()/stop()/destroy() only work properly when JBC is deployed inside JBoss AS, while createService()/startService()/stopService()/destroyService() will do what you want. See http://jira.jboss.com/jira/browse/JBCACHE-1001 and related forum thread for a discussion on why that is.
