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 Assignee: Bartosz Baranowski Priority: Major Attachments: WFLY-10268-reproducer.patch 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.
