title: Skip root element while deserializing json
body: <p>How should I deserialize following JSON to skip root element and parse just the inner part of this JSON. I'd like to avoid creating additional, 3rd class <code>Root</code>, which would include only <code>MapWrapper</code> field.</p>
  
  <pre><code>{
      "root": {
          "language": "en",
          "map": {
              "k1": {
                  "name": "n1",
              },
              "k2": {
                  "name": "n2",
              }
          }
      }
  }
  </code></pre>
  
  <p>So I'd like to have only these two classes:</p>
  
  <pre><code>class MapWrapper {
      private String language;
      private Map&lt;String, MyMapEntry&gt; map;
  }
  
  class MyMapEntry {
      String name;
  }
  </code></pre>
