Since this is an EE 8 spec, then use an EE 8 API: JASPIC. If you are
not running in Java EE, JAx-RS filter works just fine. If you want
everything to run in JAX-RS and create Servlet.next, that's probably
just not going to fly, IMO.

Our application for example might be run on Java SE, pure Servlet containers, or full Java EE server -- without knowing it. So how should it find out which filter to apply just to get the needed security?

However with OAuth 2.0, we don't want the client app to collect the credentials...we want the client app to redirect the resource owner to an authorization server to authenticate and grant access to the client app. I don't think this type of authorization on the client side lines up with JAAS.

Another challenge though is that OAuth brings another party to the transaction. Rather than just AuthN/AuthZ of the client by the resource, we also have to AuthZ the resource owner who is using the client. Specifically, we need to authorize that the resource owner has access to the resource AND that the client has been granted access to the resource on behalf of the resource owner.

>>> First, on the client side I'd love to see a method added to Invocation.builder to add an implementation of a new interface named AuthorizationProvider. This would allow implementations of AuthorizationProvider to be created for specific types of authz...like OAuth2AuthorizationProvider or BasicAuthorizationProvider. These providers would be responsible for applying necessary Authorization header (or query params?) to the invocation. What are the thoughts on adding some standard providers to the API? OAuth 2.0 for example is something that has become ubiquitous, but has a steep learning curve for developers to use properly.
