Fábio Silva created WFLY-13542: ---------------------------------- Summary: Container does not enforce bean-managed concurrency for timeout methods Key: WFLY-13542 URL: https://issues.redhat.com/browse/WFLY-13542 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 19.1.0.Final Reporter: Fábio Silva Assignee: Cheng Fang Bean-managed concurrency for @Singleton EJBs is not enforced for timeout methods annotated with @Schedule. When a timeout is fired while the previous one is still running, the timeout method is not called. Instead, WildFly logs a warning like the following: {code:java} 20:58:54,000 WARN [org.jboss.as.ejb3.timer] (EJB default - 2) WFLYEJB0043: A previous execution of timer [id=aa716284-ef7b-4bb3-a356-a8ca187255c4 timedObjectId=myweb.myweb.MySingleton auto-timer?:true persistent?:false timerService=org.jboss.as.ejb3.timerservice.TimerServiceImpl@303bd2d5 previousRun=Sun May 31 20:57:10 BRT 2020 initialExpiration=null intervalDuration(in milli sec)=0 nextExpiration=Sun May 31 20:58:54 BRT 2020 timerState=IN_TIMEOUT info=null] ScheduleExpression [second=0/1;minute=*;hour=*;dayOfMonth=*;month=*;dayOfWeek=*;year=*;timezoneID=null;start=null;end=null] is still in progress, skipping this overlapping scheduled execution at: Sun May 31 20:58:54 BRT 2020. {code} -- This message was sent by Atlassian Jira (v7.13.8#713008)
