[Webtest] jquery and webtest with htmlunit 2.8: the data necessary to complete this operation is not yet available

[Josep García]

Having upgraded to webtest R_1810, I am now have a lot of problems with
jQuery:

ERROR (com.gargoylesoftware.htmlunit.javascript.StrictErrorReporter) -
runtimeError: message=[The data necessary to complete this op
eration is not yet available.] sourceName=[
http://localhost:8081/xxxxx-web-1.4-SNAPSHOT/scripts/jquery-1.4.4.js]
line=[897] lin
eSource=[null] lineOffset=[0]

The relevant lines of jQuery is the doScroll() one from this fragment:

    try {
        // If IE is used, use the trick by Diego Perini
        // http://javascript.nwbox.com/IEContentLoaded/
        document.documentElement.doScroll("left");
    } catch(e) {
        setTimeout( doScrollCheck, 1 );
        return;
    }

Is this a bug?

No problems like this with webtest 3.0 and htmlunit 2.5.
