[ipv6] Re: SocketAddress.toString() and RFC 2732

[Chris Hegarty]

Thanks for reporting this Chris, and Alan for filing an issue to track it.

That issue is:
   https://bugs.openjdk.java.net/browse/JDK-8225499

 ( which links to the IPv6-only work that Alan mentioned )

-Chris.

I suspect this will require a small spec change to InetSocketAddress::toString. You mail is timely as there is a lot of activity going on at this time on net-dev to allow the JDK work in IPv6-only environments. I'll create an issue in JBS for this.
