"Move Field" refactoring causes calling field to change

[assdfsdafasfa]

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:

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:

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;
}
