title: JSON reader was expecting a name but found ':'. in Mongodb Java
body: <p>I am storing my data from external file to mongodb in localhost. it's quite huge dataset of volume 1.70GB with ~10 million tweets. While importing from file to mongodb it shows me the error <em>"JSON reader was expecting a name but found ':'"</em>
  I dint have any error on previous files. But this I cant figure it out. The data is just a real time collection of tweets from streaming API in a json format.</p>
  
  <pre><code>BufferedReader br = new BufferedReader(new FileReader(file));
      int counter = 0;
      String line;
  
      while ((line = br.readLine()) != null) {
          System.out.println(line);
          Document old_status = Document.parse(line);
  // If it is a deleted tweet, then continue
      if (old_status.containsKey("delete")) {
          continue;
      }
      //populate original tweets      
      Document original_status = new Document();
      if(line.contains("retweeted_status")){
      Document retweets = (Document)old_status.get("retweeted_status");
        original_status.append("status",retweets.get("text"));
        original_status.append("Likes",retweets.getInteger("favorite_count"));}}
  </code></pre>
  
  <p>its a sample code for importing data from file to mongo collection.
  Help me to solve this. I really stuck in this place and it takes my time.
  Thanks in advance.</p>
