java.nio.channels.CancelledKeyException

[aftersss]

sometimes the server throws this exception and stop working, other clients can not connect to the server again.I guess this happens when a client close the connection as soon as it is connectted.
The exception stack trace is:

This exception is timing dependent and must be expected since different threads may chancel the keys. Therefore its a bug that the exception is not caught and handled.

I will leave this thread open until i have verified that this is really everything that needs to be done.
