  /*
   * Created on Nov 29, 2003
   *
   * Test the composition of the properties files
   * - properties files exist (default, DE, NO, JA)
   * - properties files don't have duplicate keys
   * - non-default properties files have same keys as the default.
   * 
   * N.B. If there is a default resource, ResourceBundle does not detect missing resources,
   * i.e. the presence of messages.properties means that the ResourceBundle for Locale "XYZ"
   * would still be found, and have the same keys as the default. This makes it not very
   * useful for checking properties files.
   * 
   * This is why the tests use Class.getResourceAsStream() etc
   * 
   * The tests don't quite follow the normal JUnit test strategy of one test
   * per possible failure. This was done in order to make it easier to report
   * exactly why the tests failed.
