I verified the change, and it works for the Java model still. However, I wonder if it's not better to do a general check to see if isInterface is understood on the class, rather than testing for SmallTalk -- because the Gizmo could be used in other language (models) that don't have isInterface and this problem will happen again. I think I found a hint for you at https://stackoverflow.com/questions/32422955/pharo-smalltalk-how-can-i-check-if-a-message-conforms-to-a-protocol-defined-in
