How should I cancel EAP5 ejb3 timers whenever the server performs a shutdown?

Issue

I am trying to cancel EAP5 ejb3 timers whenever the server performs a shutdown

I have tried to create the following eap5 timer with a cancel in a @PreDestro annotated method ie:

@Stateless
@Depends({ "jboss.ejb:service=EJBTimerService" })
public class MyEAP5TimerBean implements MyEAP5TimerLocal {

    private static final String INFO = MyEAP5TimerBean.class.getName();

    static final AtomicLong counter = new AtomicLong();

    private static final Logger log = Logger.getLogger(MyEAP5TimerBean.class);

    @Resource
    private SessionContext sessionCtx;

    @Override
    public void startTimer() {
        TimerService timerService = sessionCtx.getTimerService();
        log.info(INFO + " timerService=" + timerService);
        timerService.createTimer(5000L, 5000L, INFO);
        log.info("created timer " + INFO);
    }

    @PreDestroy
    public void stopTimer() {
        TimerService timerService = sessionCtx.getTimerService();
        log.info(INFO + " timerService=" + timerService);
        Collection<Timer> timers = timerService.getTimers();
        for (Timer timer : timers) {
            if (timer.equals(INFO)) {
                timer.cancel();
                log.info("cancelled timer " + INFO);
            }
        }
    }

    @Timeout
    public void ejbTimeout(Timer timer) {
        long value = counter.incrementAndGet();
        log.info("timer " + INFO + " " + value);
    }

}

But this does not work.
