Hello,

I am trying to build a CAS Overlay with Acceptable Usage Policy.

An error occur while rendering the AUP page on some browser, my investigation seem to point a problem with browser locale and messages bundle : my desktop runs under Windows 10, with French (France) language preference.

Steps to reproduce

CAS Overlay Template, Branch 6.3 (Source code from https://github.com/apereo/cas-overlay-template/tree/6.3)

Manually add cas-server-support-aup-webflow dependency under the dependencies block of the Gradle build script

Configuration files and directories generated via copyCasConfiguration task

Then, add cas.acceptable-usage-policy.enabled=true

Run the server web application as an executable WAR via run, inside IntelliJ IDEA 2021.1.3 (Ultimate Edition)

Go to https://localhost:8443/cas

Google Chrome 91.0.4472.164 (Build officiel) (64 bits)

CAS redirect to AUP page, but some elements are not translated into French (messages, accept button)

Browser DevTools shows : Response Header Content-language: fr-FR

Microsoft Edge Version 91.0.864.70 (Version officielle) (64 bits)

CAS cannot redirect to AUP page : Error:
