Unfortunately in the world of Java where you have applications (or servlets
in this case) which can run on a variety of hardware and in a variety of
containers when you perform platform specific functions (such as changing
file permissions or ownerships) there isn't always a Java centric way of
doing things. You must at times cater to the platform. This is commonly
seen when querying the system properties as to if a platform uses / or \ in
it's path.
The best and most platform portability centric way is to ask the system what
it's specifics are and generate code for each one. I haven't looked at all
the ant code yet but I would believe that either the Mac OS isn't supported
for this method or it is taken care of else where.
So ironically, to be platform independent you sometimes have to code for
specific platforms from the beginning. Of course this only makes your code
platform independent for all known (and implemented) platforms at the time.
The instant a new platform comes out that does not adhear to one of your
coding standards your code breaks. But sometimes this is the only solution.
