------------------------------------

             Summary: DUCC Service Manger - race modifying autostart with "reference" start
                 Key: UIMA-2818
                 URL: https://issues.apache.org/jira/browse/UIMA-2818
             Project: UIMA
          Issue Type: Bug
          Components: DUCC
            Reporter: Jim Challenger
            Assignee: Jim Challenger


If a service registration and a job that references that service arrive simultaneously, the
service gets reference-started before autostart can kick in.  When the referenced job exits,
SM remembers the service was reference started and schedules a lingering stop.

If autostart is set, the reference-start should not cause the service to linger-stop.

To reproduce, 
	1 register a service with autostart false
	2 submit a job that starts the job by reference
	3 set autostart true after the job starts

If the bug is present the service will be linger-stopped when the job exits.  If the bug is
fixed, the service will stay active.
