start_when_directory_changed should work after the job was stopped

Current Situation

• You have a job with a start_when_directory_changed and this job will be stopped by the JobScheduler because its exit code is unequal 0.
• Then you unstop the job via JOC (<modify_order job="..." cmd="unstop"/>).
• Now the directory monitoring doesn't work.

Desired behavior

• the monitoring of the directory from start_when_directory_changed should work too after the job was stopped.

Workaround

• Configure the job with stop_on_error="no"
  job example with exit unequal 0 and stop_on_error=no

  <job  stop_on_error="no">
      <script  language="shell">
          <![CDATA[
  exit 5
          ]]>
      </script>
      <start_when_directory_changed  directory="./files" regex="\.txt$"/>
      <run_time />
  </job>
