    Description

      When setting file permissions on an existing MSDOS entry, the entry's "posixPerms" will be -1 (all 1s in binary).

      The current logic does not account for this when updating the 'external file attributes' bit, it sets the leading bits to 1 when they should be 0.

      This is a regression introduced by JDK-8322565
