the class ImageWriter method processWarningOccurred.

     * from a <code>ResourceBundle</code>.  Subclasses may use this
     * method as a convenience.
     *
     * @param imageIndex the index of the image on which the warning
     * occurred.
     * @param baseName the base name of a set of
     * <code>ResourceBundle</code>s containing localized warning
     * messages.
     * @param keyword the keyword used to index the warning message
     * within the set of <code>ResourceBundle</code>s.
     *
     * @exception IllegalArgumentException if <code>baseName</code>
     * is <code>null</code>.
     * @exception IllegalArgumentException if <code>keyword</code>
     * is <code>null</code>.
     * @exception IllegalArgumentException if no appropriate
     * <code>ResourceBundle</code> may be located.
     * @exception IllegalArgumentException if the named resource is
     * not found in the located <code>ResourceBundle</code>.
     * @exception IllegalArgumentException if the object retrieved
     * from the <code>ResourceBundle</code> is not a
     * <code>String</code>.
