On NB3.6 BufferedReader.readLine blocks and waits normally for user 
input. So with the standard java run-time enviroment (1.5.0). But 
debugging or running inside NB4.0-beta1 I got that undesired 
behaviour. Reproduce with this sample code:
import java.io.*;
public class EchoTest
{
 public static void main (String args[])
 {
  BufferedReader in = new BufferedReader(new InputStreamReader
(System.in));
  String line;
  while(true)
  {
   line="";
   try
   {
                                                                //nest
a linha ele deveria 
                                                               //parar
 esperando
                                                               //o 
usuario, mas no NB4
                                                                //nao 
para
    line = in.readLine();
   }
   catch (IOException e)
   {
    System.err.println(e.getMessage());
   }
   System.out.println(line);
  }
 }
}

Seems like ant integration doesn't provide working stdio for executed
apps.

An Ant limitation currently prevents System.in from working for forked
apps.
