Description
### Apache NetBeans version
Apache NetBeans 25
### What happened
When the "Pull Down Field" refactoring is performed using NetBeans, it causes changes to the code's behavior.
### Language / Project Type / NetBeans Component
_No response_
### How to reproduce
Code before refactoring:
```java
class A extends C {
}
class B {
void main() {
final int b = 2;
new A() {
void m() {
System.out.println(b);
}
};
}
}
class C {
protected final int b = 1;
}
```
Code after refactoring:
```java
class A extends C {
protected final int b = 1;
}
class B {
void main() {
final int b = 2;
new A() {
void m() {
System.out.println(b);
}
};
}
}
class C {
}
```
The output before code refactoring is 1, and the output after refactoring is 2. The code behavior has changed.

Research direction
Reproduce the issue by running the Pull Down Field refactoring on the supplied Java example and compare the output before and after. Start at the Pull Down Field refactoring entry point and trace how field references in the anonymous class are resolved. Done means the refactoring preserves the original behavior and the example still outputs 1.
