> FsPermissions's string constructor breaks on valid permission strings, like "1777".
> This is because FsPermission class naïvely uses UmaskParser to do it’s parsing of permissions: (from source code):
> public FsPermission(String mode) {
> this((new UmaskParser(mode)).getUMask());
> }
> The mode string UMask accepts is subtly different (esp wrt sticky bit), so parsing Umask is not the same as parsing FsPermission.
