IOException e is null [duplicate]

Exception is NULL always

I've got a strange problem with an IOException object and couldn't find an answer for this.

Code looks like this:

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();
}

Program catches IOException, but its object (e) is null. How is this possible?

- Please check the response you are getting from the Server.

- Please also take note of it... that UI work should be on UI thread and Non-UI work on the Non-UI thread, from HoneyComb Version of Android it became a rule.

- Please use a thread with handler, or AsyncTask for this kind of long time taking tasks.
