Just to clarify, no tests were run. The failure was reported by JTReg itself. As of now building Java on Windows requires IPv4.

On a side note, Microsoft created a completely new set of network interface-related APIs in Windows Vista. It looks like they could simplify our getByXXX methods, and possibly we could also use the same method to extract both IPv4 and IPv6 addresses. Do you think we could replace the pre-Vista code and start using the new functions?
