ADDITIONAL SYSTEM INFORMATION :
Tested on win 10, java "Java(TM) SE Runtime Environment (build 22+36-2370)", I believe this is not OS specific issue.

A DESCRIPTION OF THE PROBLEM :
jwebserver.exe tool prints invalid URL in case local "::1" IPv6 is used for binding.

---
Command:
jwebserver.exe -b ::1
or
jwebserver.exe -b 0:0:0:0:0:0:0:1
Incorrect URL printed:
http://0:0:0:0:0:0:0:1:8000/
---

According to RFC 2732 it should be:
http://[0:0:0:0:0:0:0:1]:8000/
OR just
http://[::1]:8000/
=================================

The issue is the first URL is not recognized by browser (when pasted to address bar) as a valid URL which triggers to "search" action (i.e. Chrome).
