Absolutely not my intent! That said, I guess I'm too dumb to understand how
that bug may be exploited in this case.
- If a `CartesianProductIterator` is passed an infinite iterable, the result
is expectedly infinite - the same was as for loop over infinite iterable is
going to be infinite.
- If a `CartesianProductIterator` is passed an iterable that is modified
while iterating over the iterator, it may or may not yield into an infinite
iterator.
- If a `CartesianProductIterator` is passed a fake iterable that always
returns reference to the `CartesianProductIterator` it was passed to
("iterating over self") - it may be infinite.
However, the infinite loop won't happen in the`CartesianProductIterator`
itself, but the `hasNext()` will always be true - so iterating over such an
iterator will be infinite, alike iterating over a "random generator" iterator.
