"Move Field" refactoring causes calling field to change

Move the field ‘b’ in class C to class A. Before refactoring, the output of the m() method is 2, and after moving, the output is 1.
Code before refactoring:
```java
public class A {
}
class B {
void main() {
final int b = 2;
new A() {
void m() {
System.out.println(b);
}
};
}
}
class C {
A a;
protected final int b = 1;
}
```
Code after refactoring:
```java
public class A {
protected final int b = 1;
}
class B {
void main() {
final int b = 2;
new A() {
void m() {
System.out.println(b);
}
};
}
}
class C {
A a;
}
```

Reproduce the Move Field refactoring using the before-and-after Java snippets in the issue, then trace the refactoring entry point and how field references are resolved in the anonymous A subclass. Done means moving b from C to A preserves the reference to B.main's local b, so m() still prints 2.
