JulianFeinauer commented on issue #10: Fixed NPE in S7PlcConnection#close. URL: https://github.com/apache/incubator-plc4x/pull/10#issuecomment-409963436 @sruehl my understanding is that netty avoids a scenario where one uses the event loop executors threads for blocking and thus, risks a deadlock. This should not be the case in this situation because the EventLoops Thread wich does the listener notification only counts down the latch. But as this solution seems uglier than it should be it is possibly a good idea to go over to the netty list and ask there (I am totally new to netty).
