A DESCRIPTION OF THE PROBLEM :
Runtime.exec() to start a new java program. The new java program should create a socket connection to another program.

The socket will connect if created and used from the static main method. It will also work if placed in a static method called from main. It will not work if I create an object and have the object execute the same code (which is what I need); it fails both times if the method is static or not static.

If I run the java program from the command line and not by using Runtime.exec, it works beautifully.

If while it is blocking I kill the first vm, then the second vm continues.


ACTUAL -
Blocking

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public class ProgA {
public static void main(String[] args) throws Exception {

Process p = rt.exec("java ProgB");
p.waitFor();
