      Investigation indicates that the Job was removed concurrently by the Job completing successfully while the UI query was being performed.

      This issue was also reported in SLING-4853 in 3.7.2 but not fixed there at the time as it was thought the exception wasn't thrown. SLING-4853 did fix a different list jobs operation.
