    <p>Dear John<br>
    </p>
    I'd appreciate your continuous efforts for the bridge between Java
    and Python.<br>
    <br>
    <br>
    I may be wrong., but I believe the number such as 4278190335 is too
    large for 32-bit integer.<br>
    This is where I think NumPy's 64-bit integer may be needed for
    compatibility (with Java's long)<br>

    <br>
    I mean wherever Java's long integer is expected,<br>
    Numpy's int64 might be of help.<br>

                everyone for looking at my code.   I think the issue

                into separate calls on the numbered on the numbered
                object, so they are not chained together.  This can be
                tested by hand modifying HelloWorld.py and removing the
