Shell jobs with min_tasks attribute are endlessly repeated

Current Situation

• The min_tasks attribute is used exclusively for API jobs. However, it could be misconfigured for shell jobs with unwanted results.
• If you configure a shelll jobs with the min_tasks attribute then the job start is endlessly repeated.

  <job  min_tasks="1">
      <script  language="shell">
  		<![CDATA[
  echo Job is running
  		]]>
  	</script>
  </job>
  

Desired Behavior

• The JobScheduler should ignore the min_tasks attribute in a shell job.

Note

• In a Java API job the min_tasks attribute can be used to improve the performance as it pre-loads the JVM, see Performance Optimization for API jobs
• The min_tasks attribute must not be used for shell jobs
