title: JSONObject is not a JSONObject
body: <p>Below is the JSON string response which I receive. I am parsing it using JSON.</p>
  
  <pre><code>String jsonString = "{\"a\":{\"b\":{\"c\":\"d\",\"e\":\"00\",\"f\":\"A\",\"g\":\"2\",\"h\":\"24\",\"i\":[{\"TypeFile\":\"232\",\"Request\":\"ere\",\"Thle\":\"999999\"},{\"TypeFile\":\"0720\",\"Request\":\"Y\",\"Thle\":\"999999\"}]},\"asd\":\"http://google.com/Itest\"}}";
  JSONObject obj1 = new JSONObject(jsonString );
  System.out.println(obj1);
  //JSONObject obj = obj1.getJSONObject("a").getJSONObject("b");
  //System.out.println(obj.getJSONArray("c"));
  JSONObject obj2 = obj1.getJSONObject("a");
  System.out.println(obj2);
  JSONObject obj3 = obj2.getJSONObject("b");
  System.out.println(obj3.get("e"));
  System.out.println(obj2.get("asd"));
  System.out.println(obj3 instanceof JSONObject);
  </code></pre>
  
  <p>I am getting the following error:</p>
  
  <pre><code>{"errorMsg": "JSONObject['b'] is not a JSONObject."}
  </code></pre>
  
  <p>What is the reason?</p>
