Description

If a class defines a default-visibility property and a subclass declares a getter and a setter for that property, the subclass cannot access super's property.

import groovy.transform.CompileStatic
import spock.lang.Specification

class Foo {
    Object myThing
}

@CompileStatic  // everything works without CompileStatic
class Bar extends Foo {
    void setMyThing(Object list) {
        super.myThing = list
    }
    
    Object getMyThing() {
        return super.myThing as List  // groovy.lang.MissingPropertyException: No such property: myThing for class: Bar
//        return super.@myThing as List  // [Static type checking] - The field Foo.myThing is not accessible
    }
}

class BarTest extends Specification {
    def "myThing"() {
        when:
            Bar bar = new Bar()
            List list = []
            bar.myThing = list
        then:
            bar.myThing.is(list)
    }
}

Live Demo

A workaround is to declare a getter and setter in the superclass.
