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

> DUCC daemon stop() is called twice
> ----------------------------------
>
> Key: UIMA-4693
> URL: https://issues.apache.org/jira/browse/UIMA-4693
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Affects Versions: 2.0.1-Ducc
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.1.0-Ducc
>
>
> It looks like stop() is called twice in DUCC daemons when shutting down due
> to a kill event.
> 1. stop() is called from the onDuccAdminKillEvent when the event arrives,
> 2. stop() is again called from the shutdown hook.
> Seems harmless but should be fixed.
