Generally, adding the "unspecified after an exception" clause in those places
seems to be the correct thing to do here.

It's kind of odd to mention "the collection" here. Iterator is defined as being
over a collection, but strictly speaking this isn't true; it can be an iterator
over anything. PrimitiveIterator doesn't say anything more specific than this,
just that it's a base for iterating primitives... and collections cannot
contain primitives.
I'm not sure what a better term for this is. Something like, "the underlying
source of the Iterator"?
