This issue is mostly meant as notification...
I'm having a scenario where I'd like to use olefile with Jython (the Java implementation of Python), which is unfortunately not 100% compatible to the CPython reference, especially when it comes to data types and number interpretations.
With a lot of debugging I managed to create prototype which is working with Jython 2.7-beta1 on Java 6 / 64-bit (unfortunately I can't use the latest Jython 2.7-beta3 as I am limited to Java 6, for which support was dropped in 2.7-beta2).
It will require a bit more polishing until I can file a pull request. Should be doable in the next days.
