>
> Currently, all the TCP based transports are using the old blocking style of
> socket.accept() to accept connections. This works "OK" except that for
> sockets that have a channel associated with them, the socket.close() doesn't
> cause it to return immediately. It still waits for the SoTimeout which is
> currently set a 2 seconds. That can cause 2 second delays for any shutdown
> which causes long, unnecessary delays, particularly in the tests.
> One possible "fix" is to drop the socket.setSoTimeout(2000) call to something
> much smaller. However, that would turn the accept thread into a more "busy
> wait" scenario which is undesirable.
> A better fix is to change the accepts for the sockets that have a
> ServerSocketChannel to use the NIO based selectors for the accept operations.
> The selector.disable()/selector.close() allows the socket and everything to
> close immediately. The result is that the NIO based tests now take the same
> amount of time as the non-NIO based tests (for which socket.close() causes
> the accept to return immediately).
> Pull request forthcoming.
