Description
A user misunderstood the syntax format for the FsPermission symbolic constructor and passed the argument "-rwr" instead of "u=rw,g=r". In 2.7 and earlier this was silently misinterpreted as mode 0777 and in 2.8 it oddly became mode 0000. In either case FsPermission should have flagged "-rwr" as an invalid argument rather than silently misinterpreting it.
