Refactoring of class member names in Java

Class member name refactoring does not work under this specific condition:

class X {
  int i;
}

X x = new X();
String newName = Integer.toString(x.i);

If you try to refactor name of the member x.i to the name of the variable on the left side (called newName), you get the following result:

String newName = Integer.toString(x.X.this.newName);
