Description

Consider the following:

package p;
abstract class A {
  private Object getX() { return "X"; }
  /*package*/ Object getY() { return "Y"; }
}

@groovy.transform.CompileStatic
class C extends p.A implements Map<String,String> {
  @Delegate Map<String,String> map = [:]
  void test() {
    print this.x // Cannot access method: getX() of class: p.A
    print this.y // IllegalAccessError: class C tried to access method p.A.getY()
  }
}

STC is happy with both property expressions since they can be satisfied via the Map interface. Classgen emits error for the private getter and writes out a call to the package-private getter. In GROOVY-11367, these are noted in #5: "this.any // getter (public, protected, package-private if same-package) or entry (private, package-private if other-package)"
