Finally, a circumvention, if not a solution, did surface:
GF opens local socket connections by using as the host what is returned from java.net.InetAddress.getLocalHost() (localhost will never be used).
In my network configuration there is a 1394 Net Adapter with an IP-adress starting with 169.254, and for some reason, and in some cases, this prohibits opening a socket connection locally through that name.
However, removing the IP-adress with ipconfig /release unblocked the pipe.
Thanks to all of you having read my post, even if no solution could be found.
