Sometimes jobs are cancelled after they have been acquired but before they are actually executed:

--> Job is acquired
--> Job is added to Queue
>>>> Job is deleted (interrupting boundary event or sth. comparable fired)
--> Job is taken from Queue and attempted to be executed
--> Process Engine throws exception

The process engine should not throw an exception here but rather fail gracefully and ignore the acquired job.

AT:

• remove Exception and replace with DEBUG logging message.
