[jboss-jira] [JBoss JIRA] (WFLY-13656) Wildfly 18 - Failed to run scheduled task - after redeployment

[ https://issues.redhat.com/browse/WFLY-13656?page=com.atlassian.jira.plugi... ] ralph Soika commented on WFLY-13656: ------------------------------------ I am sorry, but in my current environment (docker container with auto-deploy) I can not test the cli. What surprises me, is that you recommand me to use an ejb timer. I worked with EJB Timers the last 10 years. My understanding was that the ManagedScheduledExecutorService is the new recommended solution to do scheduling in Java Enterprise. Especially if I have a cluster situation with multiple nodes? I understand the ManagedScheduledExecutorService to be more robust and maybe even replacing the ejb timers in a long term? I know that if I rewrite my service with an ejb timer it will work fine. But I understand that a ejb timer will not scale if I have multiple instances running in a big kubernetes cluster because only one ejb timer instance is allowed by Jakarta EE specification. If you can tell me that this is not true, than I will switch back to ejb timers. In any case, below I send you an additional complete stacktrace from the situation when the auto (re)deployment starts. Maybe you can see in this more detailed stack trace a hint about the root that causes the problem? Thanks for your help!   {noformat} imixs-documents_1 | 18:47:13,702 INFO [javax.enterprise.resource.webcontainer.jsf.config] (Mojarra-WebResourceMonitor-1-thread-1)
