Hi all
I'm investigating H-1879 and need some help or recommendations from net
guru.
I have extracted failed test from
org.apache.harmony.tests.internal.net.www.protocol.http.HttpURLConnectionTest,
please see below. It failed with connection refused exception.
Java code works well, it looks like some problem with native code. By
the way telnet can't connect to created server too.
If somebody can help with this issue it would be great.
Thanks.

FAILURES!!!
Tests run: 1, Failures: 0, Errors: 1
The test passes on Harmony+IBMVME on WindowsXP on my desktop, so you
mean Harmony+DRLVM here?
But IMHO the VM does not matter in network issues, the native code call
directly to the system APIs(of course, through Port-Lib), so I wonder if
there's something wrong in thread(handle by VM)? Just a thought.
And IMO, that telnet shall not connect to the server is due to
"serverSocket.setSoTimeout(1000);", which make "serverSocket.accept()"
wait for only one second.
I have to download Harmony+DRLVM to debug into, but the speed of network
is poor here :)
