It used to be that checking bounds on certain collections was less
efficient than waiting for the out of bounds exception. I think Joshua
Bloch discusses this in his book.
I've also seen this in generated code where you aren't sure of the
nature of the object you're indexing and thus don't know the
appropriate length variable (.length vs .length()).
That said it's still awful.
