Apply the pull up field refactoring to a field f moves all fields f of the subclasses to the super class. If one of the fields is initialized with different value, the behavior of the program may change

Reproducible: Always

Steps to Reproduce:
1. Create the classes:

public class A {
}
public class B extends A {
  public int k = 10; 
}
public class C extends A {
  public int k = 20;
  public long test() {
    return k;
  }    
}

2. The method test returns 20 
3. Apply the pull up field refactoring to B.f

public class A {
  public int k = 10;
}
public class B extends A {   
}
public class C extends A {  
  public long test() {
    return k;
  }    
}

4. The method test returns 10 instead of 20. The refactoring changes the program behavior
