[Ziqi Z. <ziq...@sh...>]

Hi
I am testing the following code to download a webpage from wikipedia. 
and it generates a long exception as shown below. Any ideas much 
appreciated!

Thanks

Code:
-------------

final WebClient webClient =new WebClient();
try {
     final HtmlPage page = webClient.getPage("https://en.wikipedia.org/wiki/Commedia_all%27italiana");

     page.save(new File("blah/saved.html"));
     System.out.println();
}catch (Exception e){
     e.printStackTrace();
}
----------------------

Exception:
