[keycloak-user] Spring Boot Adapter: Error creating KeycloakConfigResolver with KC 4.5.0.Final

Fri Sep 28 11:41:42 EDT 2018

Here's reproducable demo: https://github.com/dasniko/kc-sb-sec-demo
Power it up and try to access http://localhost:9000/ - this will return a 500 and there's a loooong error on the console
(You even don't need a KC server running, the error happens before accessing the server)
