Makes sense, yesterday I was seeing a somewhat related issues in terms of PyLong not playing well with PyInteger in java2py adapting.

Fortunately these are usually easy, to the point of trivial, to fix, once we have identified and started testing.

Note that is one example where CPython also doesn't get it right:

$ python
