A DESCRIPTION OF THE PROBLEM :
Try to compile the provided program. No matter what you do, the program cannot be compiled. javac complains about "ambiguous method", or if you try to cast the argument of the last call to Object, that no method can be found.

Eclipse compiles the source providing the expected result (the most specific method is called).


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just compile the source provided.


ERROR MESSAGES/STACK TRACES THAT OCCUR :
> javac Test.java
Test.java:19: error: reference to method is ambiguous
c.method(Integer.valueOf(0));
^
  both method method(Integer) in B and method method(K) in A match
  where K is a type-variable:
    K extends Object declared in interface A
1 error


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
interface A<K> {
        void method(K k);
}

interface B {
        void method(Integer k);
}

interface C extends A<Integer>, B {
}

class D implements C {
        public void method(Integer i) {}
}

public class Test {
        public static void main(String args[]) {
                C c = new D();
                c.method(Integer.valueOf(0));
        }
}
