CancelledKeyException during shutdown

I am running 0.16.0 and I started getting this exception at shutdown. Just
wondering if I am maybe shutting down improperly?

20:12:42,904 DEBUG ker #4-1 ket.nio.SelectorUtil: 74 -
CancelledKeyException raised by a Selector - JDK bug?

I am only calling _server.close() at the moment. Should I be calling
close() on any clients also or doing something else?

No need to worry, seems like netty missed handling this case. Calling close on the node is enough.
