Pushing down a method to a class in another package may shadow a Class declaration leading to a behavioral change 

Reproducible: Always

Steps to Reproduce:
1. Create the classes
package p2;
public class B extends A {
}
package p1;
import p2.*;
public class B extends A {
  protected long k(  int a){
    return 0;
  }
  public long test(){
    return m();
  }
}
package p2;
import p1.*;
public class A {
  public long k(  long a){
    return 1;
  }
  public long m(){
    return new B().k(2);
  }
}
2. Apply the push down method to m()
package p1;
import p2.*;
public class B extends A {
  protected long k(  int a){
    return 0;
  }
  public long test(){
    return m();
  }
public long m() {
    return new B().k(2);
  }
}
package p2;
public class B extends A {
	public long m() {
	    return new B().k(2);
	  }
}
package p2;
import p1.*;
public class A {
  public long k(  long a){
    return 1;
  }
}
3. Before the transformation, method m() yields 1, but after that, it yields 0.
