>  private void expandStack() {
>     stack = Arrays.copyOf(stack, stack.length+Math.max(stack.length,1024));
>   }
> should probably be:
> private void expandStack() {
>     stack = Arrays.copyOf(stack, stack.length+Math.min(stack.length,1024));
>   }
> This expansion probably is intended to grow exponentially up to 1024, and not exponentially
after 1024...
