 * @bug      5017991

 * @summary  This test verifies two things:

 *            a) we can get MetadataFormat classes for

 *                each registered metadata format.

 *            b) all metadata formats for standard plugins

 *                are registered.

 * @run main RegisteredFormatsTest
