> UIMA-DUCC: Fix race in agent

> Key: UIMA-6061
> URL: https://issues.apache.org/jira/browse/UIMA-6061
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Priority: Major
> Fix For: 3.0.1-Ducc
>
>
> There is a race condition in agent which leads to incorrect process reporting
> in Duccmon. In this scenario the following happened:
> * agent started JP
> * JP reported Initializing state which agent then publishes to the OR
> * JP reported Running state but immediately after died due to process error.
> The agent detected process termination (before publishing Running to OR) and
> changed state to failed with reason Unknown
> The result is that the OR thinks that the JP died while Initializing since
> Running state was never published. There is a small window where the race can
> occur.
