Create InterfaceA:
public interface InterfaceA {
  public void methodA;
}
InterfaceB:
public interface InterfaceB extends InterfaceA {
  public void methodB;
}

create class Test:
public class Test implements InterfaceB {
}

Synchronize action should be invoked and methods methodA and methodB are
inserted into class Test.

Rename methodA in interfaceA. Synchronization should rename methodA in class
Test, but new method is added into Test class.
