Are you saying that it's impossible for any AsynchronousByteChannel
implementation to continue to use a connection after cancellation? Or were
your comments specific to AsynchronousSocketChannel?

Are you saying that no operating system supports this? Or are you saying
that some operating systems do not, hence we cannot guarantee it in a
cross-platform manner?

Thank you,
