firstPara is empty in Wiki page(Java).

[hyunsik]

Issue

Running WikiNodeExample, nothing printed in the terminal.

Cause

I guess that maybe wiki page is changed. When I saw page's DOM's tree, there was another <p class='mw-empty-elt'> element. (And there is no text.)

Solved

So I changed index 0 to 1. And I can see paragraph same the book.

// ...
Elements paras = content.select("p");
Element firstPara = paras.get(0); // if change 0 -> 1, can see same result with book.
//...

Also, I think can solve this problem through change wiki page. But I am not sure how to fix. I ever not contributed wiki page. :)
