Ronald, I haven't written a test yet, but as I read the code this is not implemented for timers. See CreateTimerAction.java. Also, relative to both this and Alex's other problem of today (http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4051686#...) I really need to write a test for this. To repeat: as I see it, if a thread is executing an exclusive job for a token, and another event comes in on the same token that spawns a job, there's nothing preventing another thread from trying to run with it, theoretically resulting in what Alex is seeing in both cases. -Ed Staub View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4051731#...
