[jboss-dev-forums] [Design of JBoss jBPM] - Re: does optimistic locking always work ?

session.load(class, id, LockMode.UPGRADE) or session.lock(processInstance, LockMode.UPGRADE) results in "SELECT ... FOR UPDATE" on databases that support pessimistic locking, this will result in a pessimistic lock. We expose the lock already in the JbpmContext (or in the persistence service, i don't remember). So users can start adding pessimistic locks themselves whenever they want to. But I want to work out a solution/workaround/fix that works by only using optimistic locking.
