An infinite loop (and eventually an OutOfMemoryError) occurs when processing this HTML:
I encountered this in the wild while parsing http://www.southmoney.com/touzilicai/waihui/201709/1626722.html.
Infinite loop started occurring in the 2.14 release.
Here's the HTML (once again eaten by sourceforge):
<time><b><li>
Thanks Michael, I'll look into it.
This seemed to be caused by some inconsistencies in the HTML5 definitions file; fixing this seems to have removed the problem.
