1. Create simple java project with 2 classes in same package:

package test;

public class ClassA {

    public void m(){
          ClassB b = new ClassB();
    }
}

package test;

public class ClassB {
    
}

2. Right click ClassA in Projects view and from pop-up menu select Refactor > Move...

3. Select destination "test" and press Refactor

>> Refactor should not allow to move class to its package (like renaming "ClassA" to "ClassA"). Useless "import test.ClassB;" has been added to ClassA despite ClassA remains in same package.
