> UIMA AS not calling AE.destroy() method on the same thread that initialized
> the AE

> Key: UIMA-2309
> URL: https://issues.apache.org/jira/browse/UIMA-2309
> Project: UIMA
> Issue Type: Bug
> Components: Async Scaleout
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Fix For: 2.4.0AS
>
>
> When stopping, UIMA AS doesnt call AE.destroy() method on the same thread
> that was used to initialize the AE. Also, UIMA AS thread factory (source of
> threads which process CASes) sets each thread as daemon resulting in a
> premature exit of a process. The jvm is free to exit if all threads complete
> their run() method or all remaining threads in the jvm are daemon threads.
> This premature exit prevents UIMA AS from completing call to destroy() method
> on each AE. Refactor code involved in UIMA AS process shutdown.
