title: Retrofit 2.0 : onResponse called with null when HTTP Code is 404
body: <p>When REST Api returns 404, onResponse called with NULL Response. We have user search api and if the user is not found on the server our REST api returns 404 with error response in body with more details.</p>
  
  <p>As Retrofit 2.0 returns a null response body, it's hard for us to show the correct error to the user.</p>
  
  <p>Do we have an alternate solution to get a response during 404?</p>
  
  <p>Response:
  {"responseStatus":{"code":"00297","severity":"ERROR","message":"Profile not found..","info":"","status":404}}</p>
  
  <p>HTTP Status Code:
  404</p>
  
  <p>Thanks</p>
