Uncaught Exception in HTMLUnit

[laDanz]

Somehow this line causes HTMLUnit (version 2.27) to crash hard. JQuery cannot be fully loaded, so further processing on my website is not possible.

jquery/src/core/support.js

Line 15 in 2d4f534

body.innerHTML = "<form></form><form></form>";

Could you please wrap it by try/catch or assert?

Somehow

That's the key thing, isn't it? There isn't enough information here to determine the problem, and having jQuery try to mask this doesn't even make sense until the "somehow" is resolved. Nobody else has reported this problem so you'll need to provide more information,

[laDanz]

Maybe the error is caused in the line above:

jquery/src/core/support.js

Line 14 in 2d4f534

var body = document.implementation.createHTMLDocument( "" ).body;

and more precisely the faulty implementation of this code at the HTMLUnit end?

We need a test case in order to assess any possible issue, preferably from jsfiddle.net or jsbin.com.
