Iterating an array is straight forward using a for loop, like you do, although I usually iterate by doing:
for(int i = 0; bag.size() > i; i++) {
...
}
But your way works too.

I need more information to answer you about the NPE.

Yes, I was looking at this as well.

The ImmutableBag should be extending Iterable like other collections.

I guess the knock on affect would mean that each concrete instance which uses it would need an iterator implementation. But it'll allow for the use of enhanced loops.
