FilePermission Canonical path optimization

[deven you]

Hi Weijun,

>From my understanding, the new proposal will let implies method only
depends on the absolute path in policy file, correct? So it's user's
responsibility to ensure files who want to access is relative to the
absolute path in some policy file?

I personal agree this proposal. Is there any doc or link for this new
proposal? Or if you can update the information for this proposal here, I
will be very appreciate!

Thanks a lot!
