title: Getting invalid scope when requesting for oauth2 access token
body: <p>I have an oauth service in my server which performs the authentication operation and issues access token when request comes for valid users.Then when i tried to request to this service using a command line curl request i am getting below error.</p>
  
  <pre><code>"detailMessage":"Invalid scope: read,write,trust","cause":{"additionalInformation":{"scope":"read trust write"}
  </code></pre>
  
  <p>Below is my request which results the error.</p>
  
  <pre><code>curl -X POST http://localhost:8080/MyProjectOauth/oauth/token -H “Accept: application/json” -d "grant_type=password&amp;client_id=client1&amp;client_secret=client1&amp;username=user1&amp;password=user1&amp;scope=read,write,trust"
  </code></pre>
  
  <p>If i tried this request without the scope then getting below error.</p>
  
  <pre><code>"detailMessage":"Bad credentials","cause":{"detailMessage":"Bad credentials"
