Ralph Johnson, a prominent Smalltalk'er, was advisor on that paper and was the creator of the first Smalltalk refactoring browser and that paper is littered with references to how things are done in Smalltalk. I was unaware a C++ was involved, but I still think Smalltalk had the first commercial refactoring browser. A research paper is not a product, however, thanks for the ref.
Don't be a douche, obviously I don't think it's the same hence my comment. And I'm willing to bet, same as you, my source was Google to verify my memory of something I read long ago.
