Second ping: rewrite File.toCanonicalPath()

[Gary Benson <gbenson at redhat dot com>]

Hi all,

A couple of months ago I posted a patch that rewrote File.toCanonicalPath()
on GNU/Posix systems in order for FilePermission checks to work properly,
so much of the security framework relies on it.  I rewrote it a couple of
times at various people's requests, but this (final?) version met with no
response whatsoever.

Can someone please approve it or tell me what's wrong with it?

As before the diff of the method itself is not very legible so I've
attached a copy of it as well as the patch.

Cheers,
Gary
