If during the static initialization of a class hierarchy,
             an active use occurs of a class that is scheduled for
             initialization, but not initialized (because the active
             use occurs during its superclass initialization), then
             the JVM crashes with a segmentation violation

             This did not happen with 1.0.2, but happens with 1.1beta1
             and 1.1beta2.

             Example code:

------------------------------
class statinit0
{
  static statinit test ;
  static
    { System.out.println ("entering static init for statinit0") ;
      test = new statinit () ;
      System.out.println ("leaving static init for statinit0") ;
    }
}

public class statinit extends statinit0
{
  static int a = 0 ;
  static int b, c ;
  static
    { System.out.println ("entering static init for statinit") ;
      b = 0 ;
      c = 7 ;
      System.out.println ("leaving static init for statinit") ;
    }


  public statinit ()
    { a ++ ;
      b ++ ;
      c ++ ;
      System.out.println ("constructor for statinit, a=" + a + " b=" + b + " c=" + c) ;
    }

  static public void main (String [] args)
    { System.out.println ("entering main") ;
      statinit s = new statinit () ;
      System.out.println ("leaving main") ;
    }
}
------------------------------

           Output under 1.0.2:

------------------------------
entering static init for statinit0
entering static init for statinit
leaving static init for statinit
constructor for statinit, a=1 b=1 c=8
leaving static init for statinit0
entering static init for statinit
leaving static init for statinit
entering main
constructor for statinit, a=2 b=1 c=8
leaving main
------------------------------

           Output under 1.1

------------------------------
entering static init for statinit0
entering static init for statinit
leaving static init for statinit
constructor for statinit, a=1 b=1 c=8
leaving static init for statinit0
