I've upgraded my enviroment to Hibernate 3.2 and JbossCache 1.4 with Java5 installed, yesterday. I changed cache locking scheme to OPTIMISTIC as it is recommended for hibernate. OPTIMISTIC But for any hibernate second level cache call to treecache it says : ... INFO [OptimisticNodeInterceptor] Cannot Handle Method _put(GlobalTransaction: .... How can I solve this? By the way changing the locking scheme back to PESSIMISTIC will solve my issue, but I really like to have the OPTIMISTIC locking scheme for the cache.
