I've talked about it with Michael Koch on IRC on #kaffe, who's familiar 
with the gcj side of the networking implementation. It seems that gcj 
does not support IPv6 at all, and noone else using Classpath apparently 
does, so the implementation in Classpath has not really been exposed to 
such an interesting usage case (one NetworkInterface name, two 
InetAddresses), thus it actually is broken in that respect.

I'll write up some code that 'condenses' the NativeInterfaces that are 
received from the native method, and I hope that will fix the breakage.
