As a general rule, there is no need to use '\' in a path for anything in Java, except when that path will be used in Runtime.exec() kinds of calls where the windows "CMD" application is involved. Windows, for many, many years, as an operating system, has supported either, and from a portability issue, using '/', instead, will make your programs more portable, especially if you do use relative paths.
Having to 'double' the '\' characters is a pain. It causes all kinds of "hard to find" problems when you don't. So, use '/' in your ConfigurationFile input, unless you really are crafting a "CMD" command line.
