      Job newJob(TriggerFiredBundle bundle, Scheduler scheduler) throws SchedulerException
      Called by the scheduler at the time of the trigger firing, in order to produce a Job instance on which to call execute.

      It should be extremely rare for this method to throw an exception - basically only the the case where there is no way at all to instantiate and prepare the Job for execution. When the exception is thrown, the Scheduler will move all triggers associated with the Job into the Trigger.STATE_ERROR state, which will require human intervention (e.g. an application restart after fixing whatever configuration problem led to the issue wih instantiating the Job.

      Parameters:
      bundle - The TriggerFiredBundle from which the JobDetail and other info relating to the trigger firing can be obtained.
      scheduler - a handle to the scheduler that is about to execute the job.
      Returns:
      the newly instantiated Job
      Throws:
      SchedulerException - if there is a problem instantiating the Job.
