> If  objectref in invokeinterface instruction refers to the class which does  not implement used interface Jitrino/OPT does not throw IncompatibaleClassChangeError.
> To reproduce this bug run the following intfTest. It invokes class intf_cl_2 which was created from jasmin code:
> ------------------intfTest.java------------------
> import java.io.*;
> public class intfTest {
>     public static void main (String[] args) {
>         try {
>              System.out.println("Test failed: " + new intf_cl_2().test());
>         } catch (IncompatibleClassChangeError e) {
>              System.out.println("Test passed: " + e);
>              e.printStackTrace();
>         } catch (Throwable e) {
>              System.out.println("Test failed: unexpected error");
>              e.printStackTrace();
>         }
>     }
> }
> -----------------------------------------------
> public interface intf_1 {
>     public abstract int intfMethod();
> }
> -----------------------------------------------
> public interface intf_2 {
>     public abstract int intfMethod();
> }
> ----------------------------------------------
> public class intf_cl_1 implements intf_1 {
>     public int intfMethod() {
>         return 105;
>     }
> }
> ---------------------------------------------
> .class public intf_cl_2
> .super java/lang/Object
> ;
> ; standard initializer
> .method public <init>()V
>    aload_0
>    invokespecial java/lang/Object/<init>()V
>    return
> .end method

>   ireturn

> ---------------------------------------------------
> Create intf_cl_2 class using jasmin.jar 
>     java -cp jasmin.jar intf_cl_2.jj
> or use class file from attachment
