Here's is a program that fails on 1.1 (NT and Solaris/AIX). It seems
serious in that it produces a very violent crash - and possibly it's gone
into an infinite loop before crashing.


public class toto implements tutu{
  public toto() {}
static public void main(String args[]){ toto myToto = new toto(); }
}
public interface tutu{
  public final static tutu ExampleImplementation = new toto();
}

The output trace is:

hoyhoy% java toto
