Arghh, the cron expression validator from quartz is bad. I'll add more test in our own validator and will check that ranges are in correct order.

Besides fixing the validator, I think codes in application startup should be fixed as well so that the application can staert up normally with invalid schedule disabled. Otherwise it is too hard for an administrator to fix the problem, since the broken schedule will completely bring down the web application and need to direct alter the databaase to change the schedule.

Can you attach stacktrace when continnuum can't start with a bad cron expression?

Fixed.
I'll close this issue when we'll use the new cron expression validator.
