Moving this to net-dev as that this where this API is maintained.

Yes, this seems an oversight as it is always problematic to read/parse a 
String that is an IPv6 literal address followed by :<port>. 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.
