Ok, I think I figured it out. But please confirm. The Rule Engine Session DOES NOT release objects. (But hten why have a Stateless session?) if the duration of use of the session is not going to be long? The solution: Pool the RuleBase and on a request createa freesh session from it each time a request comes in! Let me know if the cocept is sound or what I'm thinking is now correct.
