/**
 * Schedule unscheduled Scheduler (requires valid SchedulerEntry Data &&
 * Message Date)/*  w w w. j a  v  a  2  s .  c o m*/
 * 
 * There is no Issue in Liferay Tracker about this: Manually assembling.
 * Message, Trigger and Job from previously "working" Job, in order to use
 * 
 * SchedulerEngineHelperUtil.schedule(Trigger, StorageType, Description,
 * Destination, Message, exceptionsMaxSize);
 * 
 * Currently (6.2 GA 4 - GA 6) also fails to register the MessageListener
 * correctly for a single consumer. This might be a configuration detail
 * issue, which is not documented in liferays SchedulerEngineHelperUtil, at
 * first sight source investigation does not reveal conclusive hints.
 * 
 * Though the more complicated issue is that Quartz does persist the Job on
 * UNSCHEDULE but not the Trigger.
 * 
 * Therefore a SchedulerEntry must be available in Memory, to schedule an
 * unscheduled Job Liferay SchedulerEntry however does persit the Trigger...
 * but does not check for duplicates on deploy.
 * 
 * If we keep the SchedulerEntry in the List we have the Trigger but
 * unregister fails and duplicates the Scheduler If we remove the
 * SchedulerEntry unregister works correctly but we lose the Trigger
 * 
 * @throws ClassNotFoundException
 * @throws IllegalAccessException
 * @throws SchedulerException
 * @throws Exception
 * @throws InstantiationException
