[HtmlUnit] [htmlunit:bugs] #2012 Javascript in CDATA block causes EvaluatorException: illegally formed XML syntax

[RBRi <rb...@us...>]

As always it took some time to work on this. From my point of view this has to be handle by the parser. Have done a fix because the neko parser can already handle this.
Please have a look at twitter (https://twitter.com/HtmlUnit). Will inform about a new snapshot if available.

** [bugs:#2012] Javascript in CDATA block causes EvaluatorException: illegally formed XML syntax**

Javascript code  wrapped in an XML CDATA block within a <script> tag on a web page causes HtmlUnit to throw the following exception:

> net.sourceforge.htmlunit.corejs.javascript.EvaluatorException: illegally formed XML syntax

This can be replicated with the following Java code:

`(new net.sourceforge.htmlunit.corejs.javascript.Parser()).parse("<![CDATA[obj1.obj2.func1();]]>", "", 1);`

This occurs on web pages that use Oracle ADF (I believe this is the same problem reported in Bug #1991). These web pages are accepted by Firefox and other major browsers.

Tracing through the code, I can see that the TokenStream.getNextXMLToken() method successfully scans over the CDATA block, but then rather than processing the contents of the block, it just does:

`parser.addError("msg.XML.bad.form");`

I'm not sure why it does this, or the right way to fix it. With a little guidance, I may be able to provide a fix. Or if someone can give me one, it would be great. Otherwise, I'm being forced to use Selenium with Firefox, which is introducing other problems.
