      public class InternationalizedException
      extends Exception

  The `InternationalizedException` class adds internationalization support to the standard functionality provided by `java.lang.Exception`.

  To support internationalization, the thrower of an exception must not specify a hardcoded message string. Instead, the thrower specifies a key that identifies the message. That key is then looked up in a locale-specific `ResourceBundle` to find the actual message associated with this exception.

  This class also supports arguments to messages. The full message will be constructed using the `MessageFormat` class. For more information on internationalization, see the Java Internationalization Guide.

  This version of this class works with JDK versions prior to 1.4, since it does not assume support for exception chaining. The file `InternationalizedException.java_1_4` is a version that uses the exception chaining support built-in to JDK1.4.

  - ### Method Detail

    - #### getResourceBundleName

          public String getResourceBundleName()

      Gets the base name of the resource bundle in which the message for this exception is located.
      Returns:
        the resource bundle base name. May return `null` if this exception has no message.

    - #### getMessageKey

          public String getMessageKey()

      Gets the identifier for this exception's message. This identifier can be looked up in this exception's `ResourceBundle` to get the locale-specific message for this exception.
      Returns:

    - #### getArguments

          public Object[] getArguments()

      Gets the arguments to this exception's message. Arguments allow a `InternationalizedException` to have a compound message, made up of multiple parts that are concatenated in a language-neutral way.
      Returns:
        the arguments to this exception's message.

    - #### getMessage

          public String getMessage()

      Overrides:
        `getLocalizedMessage` in class `Throwable`
      Returns:
        this exception's detail message, localized for the default Locale.
