Converting getting JSON objects from string pulled from URL

I am trying to get JSON data from a string that I have created from data I have pulled down from a URL. So far this is what I have in my code:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final TextView tv = (TextView)findViewById(R.id.result);

        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);

        String username = "username";
        String password = "password";
        String url = "http://www.example.com/api/core/v1/my/";
        String unp = username+":"+password;


        class MyUser {
              public String firstName;
              public String lastName;
        }


        try {
            HttpClient client = new DefaultHttpClient();
            HttpGet header = new HttpGet(url);
            String encoded_login = Base64.encodeToString(unp.getBytes(), Base64.NO_WRAP);
            header.setHeader(new BasicHeader("Authorization", "Basic "+encoded_login));
            HttpResponse response = client.execute(header);
            HttpEntity entity = response.getEntity();

            BufferedReader reader = new BufferedReader(new InputStreamReader(entity.getContent()));
            for (String line; (line = reader.readLine()) != null;line.replaceAll("throw 'allowIllegalResourceCall is false.';", "")) {
                Vector<Object> vector = new Vector<Object>();
                vector.add(line);
                String result = vector.toString();


                JSONObject json = (JSONObject)new JSONParser().parse(result);
                System.out.println("name=" + json.get("name"));
                System.out.println("width=" + json.get("width"));

                System.out.println(line);
            }       


        } catch (Exception e) {
            e.printStackTrace();
            Log.d(MY_APP_TAG, "Error e: " + e);
        }

        }

This is pulling the correct json data down, but every time i try to parse the data i am getting the following:

I am new to JSON so figuring this out is proving a real big challenge so any help with this is much appreciated.

Also, the JSON data come through like this:

{
  "enabled" : true,
  "email" : "[email protected]",
  "firstName" : "example firstname",
  "lastName" : "example lastname",
  "name" : "example fullname",
  "level" : {

I know that these are JSON objects and not JSON arrays.
