Ambiguous method name xxx in class xx

[RichardHoOoOo]

Suppose I have a class A and a class B that extends A. Class B has a method foo that overrides Class A's foo.

class A {
    public A foo() {return null;}
}

class B extends A {
    public B foo() {return null;}
}

When I use the following code to get class B's foo, an exception is thrown saying soot.AmbiguousMethodException: Ambiguous method name foo in class B

SootClass B = Scene.v().loadClassAndSupport("B");
SootMethod fooB = B.getMethodByNameUnsafe("foo");

When I print all the methods in B, the output is

<B: void <init>()>
<B: B foo()>
<B: A foo()>

Since B's foo overrides A's foo, why there are two foos in B that causes the ambiguous exception?

I'd guess this is related to #1553
The java compiler probably generates a method to access that other foo of the super class, and thus, there are two methods with the same name. Personally, I'd refrain to use getMethodByNameUnsafe if possible for reasons like this. Besides, overloading methods is very common and would lead to a failure as well. I'd reference methods by their subsignature.
