Programatic created EJB calendar timer with SchedulerExpression and Start or End date failed on server restarted in EAP 7

Issue

• If a calendar timer is created programatical with a SchedulerExpression where start or end date is set a server restart will show the the following message. Why is the timestamp format wrong?
