João told me about that article yesterday. He said it has to do with nulls, so I told him you can do daft things like:-
I tried the example they showed with the raw type of List and they are incorrect; the code does not type check. As I had expected, the compiler produces a warning. What does Joshua Bloch say in Effective Java? He says you are type‑safe as long as you don't get any warnings and only write @SuppressWarnings when you are absolutely sure about it. I think they are mistaken to imply the compiler is broken.

I shall ask João for the actual paper.
