[keycloak-dev] Why is the access_token a JWT?

I'm looking at the OpenID Connect specs and what I don't understand is why is the access_token returned to my client a JWT? Shouldn't it be just a code? I'm sending a cope of "code" but there's nothing I can see that says the access_token should be a JWT other then thats what everyone seems to do.
