/*
 * 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 don't have any extra keys.
 * 
 * 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.
