    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,
       
    41  * java.util.ResourceBundle, java.lang.String, java.lang.Object...)

    43  * <p>
       
    44  * Note that methods that take a {@link Supplier Supplier&lt;String&gt;}
       
    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.
