Py4J automatically serializes any Python integer larger than 2 ^ 31 as
`LONG_TYPE`, otherwise it's `INTEGER_TYPE`. Python longs are always serialized
as `LONG_TYPE`.
I suspect my issue with Python 3 is that there is no more `long`, it's all
just `int`. This may require a fix on the Scala side to accept either an int or
a long to the appropriate constructor.
