/**
 * A fix that replaces <code>System.getProperty(xxx)</code> by Java methods:
 * <ul>
 * <li>Beware! The code doesn't any longer take the system property into account!</li>
 *
 * System.getProperties() can be overridden by calls to System.setProperty(String key, String value)
 * or with command line parameters -Dfile.separator=/
 *
 * File.separator gets the separator for the default filesystem.
 *
 * FileSystems.getDefault() gets you the default filesystem.
 * </ul>
