Jon, Threads don't share hibernate caches on the same process instance. If another thread looks at the token, it's going to have fetched it independently from the database. The database is updated when the token reaches a wait state. Me too. If subsequent actionhandlers do a signal or leaveNode, the execution is recursive. So in a loop with no wait states, each iteration grows the stack (and everything it refers to on the heap). This seems ugly, but I can't decide how bad it is. While a QA team would run into it quickly, I'm not sure it has much real-world consequence. -Ed Staub View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053715#...
