Hi guys! I didn't talk to you for a while, but I've found several new issues related to generics. Here is the first and the most annoying one: 1) Just compile the testcase with iajc and you will get "java.lang.IllegalStateException: Wrong number of type parameters supplied" Java Code: ========= public interface Generic1<T extends Number> { public void foo(T p); } public interface Generic2<T extends Number, Y extends Number> extends Generic1<T> { public void foo2(Y p); } public class Test<Y extends Number> implements Generic2<Y,Y>{ public void foo2(Y p) { } public void foo(Y p) { } } Aspect: ======= public privileged aspect TestAspect { pointcut TestInheritance(Test test) : target(test) && execution (* com.mprv.secsph.Generic1.*(..)); after (Test test) : TestInheritance(test) { System.out.println("GO Aspects!"); } } Exception: ========== iajc abort trouble in: public class com.mprv.secsph.Test extends java.lang.Object implements com.mprv.secsph.Generic2: public void <init>(): ALOAD_0 // com.mprv.secsph.Test this (line 10) INVOKESPECIAL java.lang.Object.<init> ()V

[Xlint:adviceDidNotMatch]
fix committed. Involved the code that sorts out the object hierarchy in ReferenceType taking into account that your super interface may not have the same number of type variables as you do. waiting on build.
fix available.
