I understood JP's critique to be more about mixing behaviour with data than about alternative ways of modelling inheritance.

But Java strongly encourages the mixing of data and behaviour. There is only virtual method dispatch and switch on ints/enums for efficient case analysis. We therefore need complex encodings like the Visitor pattern, if we are to avoid conflating data and behaviour. So again, I blame the language not the programmers.
