Message6405

This is probably some basic user error on my part. I understood that IPv6 was suspect due to prior JRE implementations, but I thought I would try it with the latest available versions. This is a small portion of client server code, only the client side needed to show the issue. Generally, this code works under plain python 2.7.1
I'm guessing that maybe this may be a failure just under my OS/JRE combo.
