* @bug 8140364
* @author danielfuchs
* @summary JDK implementation specific unit test for JDK internal artifacts.
* This test tests all the public API methods defined in the {@link
* java.lang.System.Logger} interface, as well as all the JDK
* internal methods defined in the
* {@link sun.util.logging.PlatformLogger.Bridge}
* interface, with loggers returned by {@link
* java.lang.System.LoggerFinder#getLogger(java.lang.String, java.lang.Class)}
* and {@link java.lang.System.LoggerFinder#getLocalizedLogger(java.lang.String,
* java.util.ResourceBundle, java.lang.Class)}
* (using both a null resource bundle and a non null resource bundle).
* It calls both the {@link java.lang.System} factory methods and
* {@link jdk.internal.logger.LazyLoggers} to obtains those loggers,
* and configure them with all possible known levels.
* @modules java.base/java.lang:open
* java.base/sun.util.logging
* java.base/jdk.internal.logger
* java.logging/sun.util.logging.internal
* @build LoggerFinderBackendTest SystemClassLoader
