I feel that I need to study more details about net testing. Also to

'a proof of concept'. I believe that this won't be a wasted effort
and it won't take too much time. I'm going to select a number of
'common testing scenarios', for example, I will try to "force a server
to send a chunked response" without creating a special resource to be
requested. And demonstrate that it is possible to run them without
external server or sophisticated internal server.
Anyway I was going to continue to work with Kerberos server stub
(because I'm not delighted with configuring external Kerberos server
in order to run unit tests) and this is a good change for me to review
this issue from another angle.

Hi Tim,
Funny. That's a test support class that is used to mock up an HTTP
server for one, admittedly large, test case method
(test_getInputStream
in tests.api.java.net.URLConnectionTest).
It is not "the server".
There are a significantly larger number of test case methods that
rely
on using the configured external HTTP/FTP/SOCKS servers to test out
their functionality.
