title: How to validate JWT token in Keycloak using Java SDK?
body: <p>I’m pretty savvy with OAuth 2/OIDC but new to Keycloak. I have a need to authenticate a user given a JWT token. </p>
  
  <p>Normally I’d hit the <code>userInfo</code> endpoint but in the Java SDK I don’t see a way to do that?
  Is there such a method call and/or a local library call that will just let me validate the JWT token string (so I don’t have to pull the public keys remotely to verify the signature?)</p>
