True.
I should have been more specific.  I'm talking about such cases as
doing ioctls on your digital synthesizer device, about libraries such
as libX11 that read from sockets, or your Java active network router
that needs access to a routing socket.  I believe that native methods
are often used for such functionality that is not supported by java.io.*.
