  <p>I've got a strange problem with an IOException object and couldn't find an answer for this.</p>
  
  <p>Code looks like this:</p>
  
  <pre><code>try { // This isn't very important part, but maybe it has something to do with a problem
    HttpResponse response = client.execute(httpGet);
    StatusLine statusLine = response.getStatusLine();
    int statusCode = statusLine.getStatusCode();
    if (statusCode == 200) {
      HttpEntity entity = response.getEntity();
      InputStream content = entity.getContent();
      BufferedReader reader = new BufferedReader(new InputStreamReader(content));
      String line;
      while ((line = reader.readLine()) != null) {
        builder.append(line);
      }
    } else {
      Log.e(ParseJSON.class.toString(), "Failed to download file");
    }
  } catch (IOException e) {
          System.out.println("I'm here in the IOException catch clause");
          e.printStackTrace(); // e is null (line 126)
  } catch (Exception e) {
          e.printStackTrace();
  }
  </code></pre>
  
  <p>Program catches <code>IOException</code>, but its object (e) is <code>null</code>. How is this possible? </p>
