Description

We recently upgraded to Groovy 2.4.6 version and running into Ambiguous method overloading for method error when setting null value. Reproducible test case:

interface A {}

interface B extends A {}

class MyClass {
   public void setSomething(A a) { }
   public void setSomething(B b) { }
}

def myClass = new MyClass()
A a = null
myClass.something = a

I'm not sure if this is similar to GROOVY-7481. Could you please suggest how to resolve this issue? Thanks.
