             Summary: TimerService sometimes doesn't invoke timers
                 Key: WFLY-10268
                 URL: https://issues.jboss.org/browse/WFLY-10268
             Project: WildFly
          Issue Type: Bug
          Components: EJB
    Affects Versions: 12.0.0.Final
            Reporter: Rich DiCroce


The EJB TimerService seems to have a nasty race condition where a scheduled task never gets invoked.

Because it's racy, it's hard to reproduce, but I've seen it happen fairly often by scheduling a single-action timer with a duration of zero (i.e. should be executed immediately).

Based on another problem I've been debugging in our application, I suspect that this issue affects all timers, including ones created using the Schedule annotation.
