/**
 * Exception to indicate the calling page must cease evaluation.
 * Thrown by a simple tag handler to indicate that the remainder of 
 * the page must not be evaluated.  The result is propagated back to
 * the pagein the case where one tag invokes another (as can be
 * the case with tag files).  The effect is similar to that of a 
 * Classic Tag Handler returning Tag.SKIP_PAGE from doEndTag().
 * Jsp Fragments may also throw this exception.  This exception
 * should not be thrown manually in a JSP page or tag file - the behavior is
 * undefined.  The exception is intended to be thrown inside 
 * SimpleTag handlers and in JSP fragments.
 *
