AT:

• A job definition's priority is editable in ManagementService
• When a job definition's priority has been changed (i.e. it is not the same as specified in the BPMN XML), it overrides the priority defined in the BPMN XML and the process-instance-specific priority
• The priority update can be optionally applied to existing jobs of the definition
• authorization is checked when changing the priority

Implementation notes:

• job definition table has a PRIORITY_ column
• The default JobProrityProvider implementation makes use of this
• There is a cascade option that also changes existing jobs' priorities (as a batch update without provoking optimistic locking)
