getLocalHost and localhost fail

Hi,

I get an issue with getLocalHost. I trace and I see getLocalHostname
return localhost and after the call at getbyname, getallbyname then
getHostbyName !?! and fails. I see with strace a request to the
nameserver ?!?

My question why the nameserver is called to resolv localhost ?

Why in InetAddress.java l.579 the test:
if (hostname == null || hostname.length() == 0)

is not
if (hostname == null || hostname.length() == 0 || "locahost".equals(hostname))

Thanks for your light.

Cheers,
Claude
