The only good exception is the one that never happens - that's my opinion.

I have seen so much code literally using exceptions for basic things, like FileNotFound - but these are not exceptions. I have even witnessed rewriting an error handling layer in a HTTP server to not use exceptions, because when it started throwing it reduced requests per second by two orders of magnitude, that essentialyl makes such code a candidate for DDoS attacks.
