Bartosz Baranowski commented on WFLY-10268:
-------------------------------------------

Unfortunately  Im unable to reproduce - though, given latency I thought I could. Given spam it takes timers to invoker EJB, still all of them come through. If you can isolate reproducer please reopen.

> 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.
