I recently tried to update some parameters for job schedules, but none of them used the updated parameters on it's next run.
But I noticed this stack trace which actually sounds like it might be related to this, even though it's not about one of the updated schedules itself:
2011-11-15 02:40:00,020 [[...]-SimpleThreadPoolWorker-1] INFO  o.e.g.j.i.scheduler.SchedulingJob    [...A]             - Re-creating job configuration parameter for job [...A] because they have been updated in the schedule.

However...I got the stack trace just once and updated a bunch of schedules.

Reproducible: Always
