title: Hazelcast Rest API returns no content
body: <p>Running hazelcast (3.4) on linux (rh).
  I've created MAP in one instance, added couple records:</p>
  
  <pre><code>HazelcastInstance hz = Hazelcast.newHazelcastInstance();
  IMap&lt;String,Event&gt; map = hz.getMap("EVENTS");
  </code></pre>
  
  <p>I'm able to read map using java client, HazelcastClient, but not
  able to see anything when hitting REST interface with curl or browser:</p>
  
  <pre><code>curl -X GET http://localhost:5701/hazelcast/rest/maps/EVENTS/
  </code></pre>
  
  <p>in fact browser shows response code 204 - no content</p>
