Hi all,
I finally organized an S7 to play around a bit more with Plc4J and observed the
following exception that is always thrown when calling close on the
S7PlcConnection:
17:04:54.438 [nioEventLoopGroup-2-1] WARN i.n.util.concurrent.DefaultPromise -
An exception was thrown by

Is this due to some problems on my side or my S7 or is this a hint to a bug?
Best
