FilePermission Canonical path optimization

[deven you]

Hi Weijun,

I see JDK-4141872 <https://bugs.openjdk.java.net/browse/JDK-4141872> marked
as Not an Issue, is there any further task continue, or there is any link
else to track this problem to remove the canonical path?

It's a big improvement if canonical path can be totally removed but I can't
figure out how we get the result of the implies* methods without canonical
path? Any more detail?

Thanks a lot!
