/**
   When this tool is used with long path names on Windows, that is paths which start
   with \\?\, then the caller must make sure that the path is unique. This is achieved
   by removing '.' and '..' from the path. Paths which are created by
   osl_getSystemPathFromFileURL fulfill this requirement. This is necessary because
   lucene is patched to not use File.getCanonicalPath. See long_path.patch in the lucene
   module.
