title: Facebook graph api returns 400 bad request with correct access token
body: <p>I just manually implemented a facebook oauth2 flow into my webapp. After receiving the correct access_token and trying to call the graph api for user data I got a 400 BAD REQUEST as response. </p>
  
  <pre><code>GET https://graph.facebook.com/me?accessToken=MY_CORRECT_TOKEN&amp;fields=id,name,email
  </code></pre>
  
  <p>When I use exactly the same call within the dev tools provided on facebook it succeeds, but when I try using any other http client it doesnt work. 
  I already tried it with curl, apache commons and some other http clients.</p>
  
  <p>Is there someone able to help me with this?</p>
  
  <p>Thanks in advance</p>
