Step 1: Create the class.

public class A {
	
	public long k(long a) {
		return 10;
	}
	
	public long n(String a) {
		return 20;
	}
}

Step 2: apply the rename method to rename n to k. Eclipse will show a warning: Hierarchy declares a method k with the same number of parameters but different parameter type name. 

It would be nice if the tool could analyze wether the different parameter type represent a risk to behavioral preservation. In that case, for instance, we cannot have an implicit type conversion from string to long that could change a method invokation k(2) from k(long) to k(string). So the transformation is safe, we do not need a warning.
