RFR: 7180557 - InetAddress.getLocalHost throws UnknownHostException on java7u5 on OSX

[Bernd Eckenfels]

Hello,

I reported before, AI_CANONNAME is used in different places with no good  
reason. If you use the flag, the result would be in res[0].ai_canonname,  
which is not used. So you can remove it and safe the elaborate resolving  
which comes with it.

And I also think the comment "skip DNS lookup" is wrong, as GAI typically  
(also) looks in /etc/hosts - and this is also documented in the mac os man  
page.

So I think if you remove the flag you dont need the lookupIflocalhost  
shortcut at all (or you need it on all systems).

And if you have a look there, I think the AI_ADDRCONFIG should be  
considered, instead.

Gruss
Bernd
