[keycloak-user] Keycloak 1.2.0 Beta1 and CORS

Hello, Has somebody experience with the new 1.2.0 Beta1 release in combination with CORS. I have a very simple html page (for testing purposes) that I have made available via keycloak. When I configure this page to use a Keycloak 1.1.0 Final as authentication front end all works like expected. When I configure the same page with a Keycloak 1.2.0 Beta1 authentication front end (exact the same configuration) I am not able to access my test html file. Suggestions are highly appreciated.
