Overloading not accounting for arguments type for state transitions #134
Description
I think there's a bug in selecting the correct method to check when there are two methods with the same number of arguments but different types.
This was the example where I encountered the issue.
This class has two constructors with only 1 argument, but they go to different states. With the first, it's okay to call initCause, with the second, it is not.
@StateSet({"start", "hasMessage", "hasCause"})
@ExternalRefinementsFor("java.lang.Throwable")
public interface ThrowableRefinements {
// ##### Constructors #######
@StateRefinement(to="hasMessage(this)")
public void Throwable(String message);
@StateRefinement(to="hasCause(this)")
public void Throwable(Throwable cause);
@StateRefinement(from="!hasCause(this)", to="hasCause(this)")
public Throwable initCause(Throwable cause);
}Tests where we can see the issue:
public class Test{
void test3(){
Throwable t = new Throwable("Example");
t.initCause(null);
t.getCause();
}
void test4(){
Throwable originT = new Throwable();
Throwable t = new Throwable(originT); // should be an error but its not
t.initCause(null);
t.getCause();
}
}Now, what leads me to think this is an issue in selecting the methods is that we get errors in both test cases if:
- we remove the constructor with string
- change the order of the two constructors

Yep, I mentioned this problem in #62:
Thanks for opening the issue!
