@Schedule timer cause server systemException

Question

I've a ticker method in a singleton bean that tick every minute using the following @Schdule annotation:

@Schedule(minute = "*/1", hour = "*", persistent = false)
public void tick() {
            for (ScheduledTask scheduledTask : scheduledTasks) {
                    logger.info("Start Task [" + scheduledTask.toString() + "]");
                    taskHandler.handleScheduledTask(scheduledTask);
                }
            }

where taskHandler is another singletone bean and the following is handleScheduledTask method:

@Override
@Asynchronous
public void handleScheduledTask(ScheduledTask task) {
         .
         .
         .
 // handle the scheduled task ....
         .

}

However, sometimes the tick method may called after 2 minutes. In this case, the following error arise in server log and tick method isn't called anymore

I've worked around this problem by persist the Scheduler timer:

@Schedule(minute = "*/1", hour = "*", persistent = true)
public void tick() {
            for (ScheduledTask scheduledTask : scheduledTasks) {
                    logger.info("Start Task [" + scheduledTask.toString() + "]");
                    taskHandler.handleScheduledTask(scheduledTask);
                }
            }

Until now this solve the problem and the tick method execute every minute
