I found a bug in Inet6Adress.isIPv4CompatibleAddress(). While parsing
correctly uses the ::ffff:<IPv4> format, isIPv4CompatibleAddress()
checks for ::<IPv4> instead.
The notion "IPv4-compatible IPv6 address" is different to "IPv4-mapped
IPv6 address". I think the RFCs on the IPv6 addressing architecture
deprecated the former a long time ago and maybe isIPv4CompatibleAddress
should be deprecated too. The net-dev mailing list is the best place to
discuss this topic (which is timely as there seems to be interest there
in recent time to improve the IPv6 support).
