IPv6 Nameservers in resolv.conf

[Guenther Niess]

Hi,
Linux systems don't require and moreover don't allow to use IPv6
literal host names within delimiting brackets for nameservers in
/etc/resolv.conf. So IPv6 entries have the form:
  nameserver 2001:0db8:85a3:08d3:1319:8a2e:0370:7344
Now, when I try to use a nameserver a NumberFormatException is thrown:
java.lang.NumberFormatException: For input string: "0db8:85a3:08d3:1319:8a2e:0370:7344"
  at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)

  at javax.naming.directory.InitialDirContext.getAttributes(InitialDirContext.java:140)
  at NSLookup.main(NSLookup.java:14)

So I think the JDK should handle IPv6 nameservers and therefore I
attached a small patch which works fine for me.

PS: I submitted a bug report on bugs.sun.com two months ago (Review ID:
1854941) with no response. So I'm trying this list, maybe the bug 
database isn't used any more.
