(follow up from same dev group as szkazmi) What versions of JBoss / JBossCache are required to make this call? We are currently using JBoss 4.0.3SP1 and JBossCache 1.4.0SP1. Currently we are using the TreeCacheMBean mechanism of interfacing with JBossCache. Does the markNodeCurrentlyInUse call asynchronously update the nodes across the cluster? We would like to be able to reset the ttl timestamp across the cluster but ideally we wouldn't want our transaction to wait for this update to complete.
