org.jboss.varia.scheduler.ScheduleManager.ScheduleInstance.stop() called twice ------------------------------------------------------------------------------ Key: JBAS-3127 URL: http://jira.jboss.com/jira/browse/JBAS-3127 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Scheduling/Timers Affects Versions: JBossAS-4.0.3 SP1 Reporter: Dimitris Andreadis Priority: Minor Fix For: JBossAS-4.2.1.CR1 A bogus exception is thrown when shutting down the server in the all (clusterred) configuration: 21:03:16,609 INFO [Server] Runtime shutdown hook called, forceHalt: true 21:03:16,609 INFO [Server] JBoss SHUTDOWN: Undeploying all packages 21:03:16,619 ERROR [ScheduleManager] Could not stop a Schedule javax.management.ListenerNotFoundException: Listener not found org.jboss.varia.s cheduler.ScheduleManager$MBeanListener@9d2f26 for object name jboss:service=Timer at org.jboss.mx.notification.MBeanServerListenerRegistry.remove(MBeanServerListenerRegistry.java:139) at org.jboss.mx.server.MBeanServerImpl.removeNotificationListener(MBeanServerImpl.java:820) at org.jboss.varia.scheduler.ScheduleManager$ScheduleInstance.stop(ScheduleManager.java:835) at org.jboss.varia.scheduler.ScheduleManager.removeSchedule(ScheduleManager.java:325) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ... The problem can be demonstrated by uncommenting the single schedule provider example, then letting the schedule execute its 10 repetitions, then stop the server. By looking in the code ScheduleInstance.stop() is called twice: a) when a schedule has expired b) when the schedule provider deregisters.
