it's not that simple, you must also run your app on a windows machine ,
whenever you do any major modules, as there is always something else.
it relates to calling classes, depending on where and what type you init
variables & statics, you can cause problems.
also mac seems to drop packages & jar refs, a lot faster when they are not in
use. ( closes the files) Windows seems to hold onto them forever, once you
ref a jar, it seems the file is "locked" open for the life of the app.
here seems to be one problem
in theory when you start the application , it makes sense to get the current
user name, and lock it down.
// public static String theUser =
System.getProperty("user.name").substring(0,9); //max of 10 chars ( do not do
this it fails on anything but mac)
another serious issue relates to the language kits, in java you are supposed
to be able to "lock" to a specific language or disable foreign language
input, at textfield/area level.
on the mac it is impossible, and you can actually do some major damage to
backend databases. ( try it on any java app,running on a mac)
( in mac you can switch languages at will) ,but java on mac has no way to
prevent this. ( i asked apple to add a couple of system calls to the
"apple.java" library 1 year ago, to allow a java app to disable language
input.
