groovy3: setProperty does not work in sub classes

class A {
    def a = "a";
}

class B extends A {
    
}

class C extends B {
    void setProperty(String name, Object value) {
        super.setProperty(name, value);
    }
}

def newC = new C();
newC.setProperty("a", "b");
newC.a
 

groovy.lang.MissingMethodException: No signature of method: B.setProperty() is applicable for argument types: (String, String) values: [a, b]
Possible solutions: hasProperty(java.lang.String), getProperties()
