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.
