Review Comment:
Good point ! My motivation here is to keep the option as simple and
straightforward as possible. Having an upper bound ( I am assuming you meant
setting default value of param MAX_FILES_TO_REWRITE as LONG.MAX_VALUE) which
would add a side effect to this functionality by limiting the number of file
to 2^^63-1 . However unlikely that is, I dont believe optional parameters
should interfere in the default behavior and isolate for the sake of
consistency and clarity.
