Isn't this just because in your /etc/hosts file (or
c:/windows/system32/drivers/etc/hosts) you have a mapping
127.0.0.1 ntsdrlew31/10.125.122.60 localhost
? It's pretty much always localhost that's returned by default.

Alexei,
Unfortunatelly this patch didn't help. Because system have already
returned host name as "nstdrlew21.ins.intel.com".
Certainly we can hardcode 127.0.0.1 as localhost
if (address == 0x7f000001) {
hostName = "localhost";
} else {
hostName = getHostByAddrImpl(ipaddress).hostName;
// ask system
}
and we will get on Harmony
by name (127.0.0.1) -> localhost
by name (localhost) -> localhost
by address -> localhost
localhost -> nstdrlew21/10.125.122.60
But I am not sure this is correct.
