------------------------------------

             Summary: Hot-Deploy throws IllegalStateException: Timer already cancelled
                 Key: WFLY-12390
                 URL: https://issues.jboss.org/browse/WFLY-12390
             Project: WildFly
          Issue Type: Bug
          Components: EE
    Affects Versions: 17.0.1.Final
         Environment: any OS
single Wildfly 17 (not yet in production)
            Reporter: David Schmidt
            Assignee: Brian Stansberry


I did an Upgrade from 11 to 17.0.1 and now I'm getting IllegalStateException on hot-deploys.

What I tried without result:
* truncate the jboss_ejb_timer table (to remove existing)
* remove all old @Schedule and add a new different timer
* use @Resource TimerService instead of @Schedule

restart allows to deploy again (for a time)

As it happens in programming, I can't reproduce this at the moment. I got tormented for weeks but today it doesn't happen...
