[jboss-user] [EJB 3.0] - Timer service

After deploying timer service on JBOSS APS 4.0.4.GA, method annoted with @Timeout is always called twice. 
It seems to be bug.

When I call destroy method (which calls cncel() on all timers from given TimerService) from jmx console and start this service again with create method from jmx console everything works fine. @Timeout annoted method is called only once.

Code of the bean:

@Service(objectName = "deplplugin:service=myLoader")
@Management(MyTimerLoader.class)
public class MyTimerLoaderBean implements MyTimerLoader {
    
    Queue queue = null;

    
    @Resource 
    private SessionContext ctx;

    TimerService timerService;
    
    
    public void create() {
        timerService = ctx.getTimerService();
        Timer timer = timerService.createTimer(new Date(), 3000, null);
    }
    
    @Timeout
    public void periodicallyRead(Timer timer) {
        System.out.println(">>> run");
    }
    
 
   public void destroy() {

        if(timerService != null) {
            
            Iterator iter = timerService.getTimers().iterator();
            
            while(iter.hasNext()){
                ((Timer)iter.next()).cancel();
            }
        }
           
    }
}

Output after deployment is:

16:25:04,641 INFO  [STDOUT] >>> run
16:25:04,641 INFO  [STDOUT] >>> run
16:25:19,626 INFO  [STDOUT] >>> run
16:25:19,626 INFO  [STDOUT] >>> run
....

and should be:

16:25:04,641 INFO  [STDOUT] >>> run
16:25:19,626 INFO  [STDOUT] >>> run
....


During undeployment of jar package theare is following exception:
