retrieving the next object raises the possibility of an exception
being thrown, this method allows that exception to propagate back
to the JSP container as a JspTagException; a standalone Iterator
would not be able to do this. (This explains why LoopTagSupport
does not simply call for an Iterator from its subtags.)</p></div>
