> After fixing IGNITE-15367 calling {{GridNioServer$AbstractNioClientWorker.closekey(SelectionKey key)}} would produce excessive {{java.nio.channels.ClosedChannelException}} because {{sock.shutdownInput()}} and {{sock.shutdownInput()}} would be called twice:
> {code:java}
> // GridNioServer$AbstractNioClientWorker
> private void closeKey(SelectionKey key) {
>     // Shutdown input and output so that remote client will see correct socket close.
>     Socket sock = ((SocketChannel)key.channel()).socket();
>     try {
>         try {
>             sock.shutdownInput();           // <-- First time
>         }
>         catch (IOException ignored) {
>             // No-op.
>         }
>         try {
>             sock.shutdownOutput();          // <-- First time
>         }
>         catch (IOException ignored) {
>             // No-op.
>         }
>     }
>     finally {
>         U.close(key, log);                  // <-- Second time
>         U.close(sock, log);                 // <-- Second time
>     }
> }
> {code}
