 * Integration tests that investigate the applicability of JSR-250 lifecycle
 * annotations in test classes.
 *
 * <p>This class does not really contain actual <em>tests</em> per se. Rather it
 * can be used to empirically verify the expected log output (see below). In
 * order to see the log output, one would naturally need to ensure that the
 * logger category for this class is enabled at {@code INFO} level.
 *
 * <h4>Expected Log Output</h4>
 * <pre>
