Ok, I think I understand. When I do a remote debug, the `CatchAllFilter` is
executing, but I believe because all of the requests I was trying would end in
failure or an expected outcome, the `message-page.jsp` wasn't getting rendered.
In that case, yes, I believe we need a similar interceptor for that response
page. I'll push another commit tomorrow. ---
