             Summary: ADS driver does not shutdown all threads (hangs) after closing connection
                 Key: PLC4X-172
                 URL: https://issues.apache.org/jira/browse/PLC4X-172
             Project: Apache PLC4X
          Issue Type: Bug
          Components: Driver-ADS
    Affects Versions: 0.7.0
            Reporter: Jens Vagts
         Attachments: Plc4xAdsTestInitial.java, image-2020-02-04-11-58-40-364.png

I'm starting to use the ADS protocol support of the PLC4X project. I succeeded to read out single values but always struggle with a hanging application process due to remaning threads of {{nioEventLoopGroup}} and {{pool-1}}.

Attached are the simple java test method and the trace log.

I build the library version 0.7-SN from source.

After 30 seconds warnings get logged regarding timeouts but the thread keep running:
