Does "aaaa" represent the host name? I'm thinking not, or it should work. Are you using FIELD granularity replication? If not, set "UseMarshalling" and "InactiveOnStartup" to false in deploy/tc5-cluster.sar/META-INF/jboss-service.xml. If you are using FIELD, your only option is to alter JBossCacheService.start() to escape the webAppPath_ field, replacing the 2nd '/' with some character that's not valid in a context path. This will prevent JBoss Cache from interpreting the '/' as an Fqn divider. (I suspect this is how you already patched it.)
