This is a really hard one - but finally i found a solution. Version 3.0.0 will include a fix - you can follow https://github.com/HtmlUnit/htmlunit/issues/552 for the progress.

** [bugs:#1968] Function.prototype.toString shall return actual source code**

**Status:** accepted
**Group:** 2.31

Some scripts make use of Function.prototype.toString  and rely on it beeing the original source code especially newlines. This is due to some pattern matching done later via regexp. This breaks with the unparsing/decompiling that HTMLUNIT does.

I therefore propose to store the original JS source and directly return it.

This is the same as browsers do. Example: https://bugzilla.mozilla.org/show_bug.cgi?id=761723
