Description

I have a ModalDialog with a form for changing my password and an AjaxButton to submit the request. The application is running with https, I am using Apache https and Apache Tomcat. This works fine with Wicket 9.0.0.

I changed to Wicket 9.1.0 and there I am getting an Exception:

In Chrome I see a 502 error.

 

Did I miss to make any changes to switch from Wicket 9.0.0 to 9.1.0 or is this a bug?
