eric-milles commented on PR #1767:
URL: https://github.com/apache/groovy/pull/1767#issuecomment-2528805577
For circumstances that go through `ScriptBytecodeAdapter`, the sender class
is not propagated to `MetaClassImpl`. Access checks give different results,
since the sender is re-mapped to the object.

```groovy
package p
class A {}
class B {}
class C {
boolean setter
protected A foo = new A()
A getFooA() { return this.@foo }
void setFoo(A a) { setter = true; this.@foo = a }
}
class D extends C {
protected B foo = new B() // hides A#foo; should hide
A#setFoo in subclasses
B getFooB() { return this.@foo }
}
```
```groovy
import p.*
class E extends D {}
def e = new E()
e.foo = null // not the field from this perspective
assert e.setter // fails
```
