default void logApplicationPackage(Level level, String message) {
        log(level, message);
    }
Log a message related to the application package. These messages should be actionable by the user, f.ex. to
signal usage of invalid/deprecated syntax.
This default implementation just forwards to {@link #log(Level, String)}
