OpenId Connect and JWT Access Tokens

[Rémi Alvergnat]

With CAS 5.2.0, how to implement OpenId Connect with JWT access_token ? Currently, id_token are JWT, but access_token are not. 

I would like the access_token be a JWT for the resource server to validate it without performing an HTTP query to CAS userinfo endpoint.

(It seems possible by implementing a custom AccessTokenFactory, but maybe there's a more simple way to achieve this ?)
