Inventory throws Exception "could not execute statement: 1048 Column 'ORDERING' cannot be null"

Current Situation
The Exception could not execute statement: 1048 Column 'ORDERING' cannot be null occurs when starting the JobScheduler with an existing process class with more than one "remote schedulers" and the URI of one of the remote schedulers consist of upper AND lower case letters.

Desired Behavior
The spelling of the URL in the process class should have no effect in determining the ordering of the agents. No error should occur.

Workaround
If the error occurs at starttime, an update of the folder (e.g. renaming) containing the process class or of the process class itself (e.g. adding a blank, removing the blank and save) will trigger the event processing and update the DB entries without an error.
