Jerry Cwiklik resolved UIMA-3232.
---------------------------------

    Resolution: Not A Problem

Turns out that the Service Wrapper's parent class does register ShutdownHook 
which *does* call quiesceAndStop. No changes are necessary

>             Project: UIMA
>          Issue Type: Bug
>          Components: DUCC
>            Reporter: Jerry Cwiklik
>            Assignee: Jerry Cwiklik
>             Fix For: 1.0-Ducc
>
>
> Check the ducc service wrapper used to deploy java processes as it appears 
> that while handling SIGTERM, the stopService() method is not being called. 
> The consequence is that the quiesceAndStop() is never invoked, preventing 
> appropriate cleanup from being done by AEs.
