49 * What is not good about this class is that once a value has been set for pdpProperties path
50 * you cannot change it. That may be ok for a highly controlled production environment in which
51 * nothing changes, but not a very good implementation.
53 * The reset() method has been added to assist with the above problem in order to
54 * acquire >80% JUnit code coverage.
56 * This static class doesn't really check a PDP, it simply loads a properties file and tried
57 * to ensure that a valid URL exists for a PDP along with user/password.
