      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      public class TestJdmc {

      public static void main(String[] args) throws IOException {
      // TODO Auto-generated method stub

      System.out.println("what a mystery file!!!");


      int iThisChar = System.in.read();
      if(iThisChar!=121 && iThisChar!=110)
      {
      System.out.println("please enter y or n");
      }


      }

      }

      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      running same class using java (1.7.0)71) PID is NOT created.
