I used Jenkins & White for an undergraduate optics class in 1984. We used the 4'th edition published in 1976, but I imagine it is essentially the same as that 3rd edition you referred to.
Feel free to identify the chapter and section number that talks about a "unit vector catastrophe", but I can't find it in that book, nor have I ever heard of that phrase.
The only "catastrophe" I've every heard of that in any way relates to what you are talking about is the "ultraviolet catastrophe". If this is what you are referring to, then (as I mentioned above) I basically agree with you. The ultraviolet catastrophe relates to a prediction of classical electromagnetic theory that does not agree with experiments, and is in fact wrong. As I mentioned, what is missing from classical theory is quantum physics, and the ultraviolet catastrophe can only be resolved by using quantum theory.
Anyway, it's no fun trying to guess what you are talking about, so if you have a genuine question or comment, please be clearer about what you are trying to ask or say.
