> When analyzing a method with exception handler, printing the exception handler block caused a NullPointerException here (line 248):
> protected void toString2(StringBuffer sbuf) {
>             super.toString2(sbuf);
>             sbuf.append(", incoming{");
>             for (int i = 0; i < entrances.length; i++)
>                 sbuf.append(entrances[i].position).append(", ");
>             sbuf.append("}");
>         }
> It appears catcher blocks have a single predecessor (instead of 0) that is "null".
