> I have found the following very simple class to be accepted by the JustIce
> verifier (BCEL 5.2) even though it should clearly not.
> $$$ javap -c Test
> Compiled from "Test.java"
> public class Test extends java.lang.Object{
> public Test();
> Code:
> 0: aload_0
> 1: invokespecial #9; //Method java/lang/Object."<init>":()V
> 4: return
> public java.lang.String foo(java.lang.String, java.lang.Integer);
> Code:
> 0: aload_2
> 1: areturn
> }
> In the method "foo", an Integer is returned instead of a String but JustIce does
> not complain about that. The Sun verifier rejects the class.
