Kyle Cho commented on HARMONY-6216:
-----------------------------------

found that the patch breaks the following test case.

  public static void main(String args[])
  {
    BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
    String line = null;
    try {
      line = reader.readLine();
    } catch (IOException e) {
      e.printStackTrace();
    }
    System.out.println(line);
  }
