code: public static final void useVerboseConsoleLoggers() {
  		String name = LoggerFactory.class.getName();
  		LoggerFactory loggerFactory = new ConsoleLoggerFactory(true);
  		loggerFactory.getLogger(name).debug("Using Verbose Console logging");
  		LOGGER_FACTORY = loggerFactory;
  	}
docs: Force the usage of Console-based {@link Logger Loggers}, even if SLF4J is available
  on the classpath. Console loggers will output {@link Logger#error(String) ERROR} and
  {@link Logger#warn(String) WARN} levels to {@link System#err} and levels below to
  {@link System#out}. All levels (including TRACE and DEBUG) are considered enabled.
  <p>
  The previously active logger factory is simply replaced without
  any particular clean-up.
