Description

A class defined as

@groovy.transform.Sortable
class ClassUnderTest { 
    String name
    int age
    int compareTo(Object o) { 42 }
    int compareTo(ClassUnderTest o) { 42 }
}

Will override the second definition of compareTo every single time.

In contrast with @Canonical for example where explicit toString() is not overridden.
