Enable IPv6

[Bob McConnell]

How do I tell Netty to listen for TCP connections on both IPv4 and IPv6?
I am currently getting this exception when I try to bind a server to
local address "::".

The application is running on MS-Windows Server 2008R2 Standard, SP1.
Netty is version 3.1.5.GA.
JRE build 1.6.0_29-b11.

Thank you,
