[Htmlunit-user] Can't disable errors

[François D. <fdu...@ez...>]

Hi,
I want to check some webpages for a specific request to be thrown.
I can’t change the source code of this pages because those are not mines but my partners ones.
On some of them, there’s errors that interrupt the script.
Even with 

WebClient webClient = new WebClient(BrowserVersion.CHROME);
webClient.getOptions().setThrowExceptionOnFailingStatusCode(false);
webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.getOptions().setPrintContentOnFailingStatusCode(false);

I have stack traces in logs and 
 com.gargoylesoftware.htmlunit.javascript.JavaScriptEngine handleJavaScriptException

What can I do ?
Thanks
