title: Jersey serializing null values to json : How to skip
body: <p>I am using Jersey 2.4 with spring. </p>
  
  <p>When I am returning a response from a method with an annotation <code>@Produces(MediaType.APPLICATION_JSON)</code> on it, it also serialize the null values to json.</p>
  
  <p>I don't want to serialize the fields that contains the null values.</p>
  
  <p>Is there any solution for the same?</p>
