35 * This implementation of {@link Logger} redirects all logging method

37 * methods, passing the Logger's ResourceBundle as parameter.
38 * So for instance a call to {@link Logger#log(Level, String)
39 * log(Level.INFO, msg)} will be redirected
40 * to a call to {@link #log(java.lang.System.Logger.Level,

42 * this.log(Level.INFO, this.bundle, msg, (Object[]) null)}.
43 * <p>
44 * Note that methods that take a {@link Supplier Supplier<String>}
45 * or an Object are not redirected. It is assumed that a string returned
46 * by a {@code Supplier<String>} is already localized, or cannot be localized.
47 *
48 * @param <L> Type of the wrapped Logger: {@code Logger} or an
49 * extension of the {@code Logger} interface.
