Java doesn't have an equivalent for unsigned types, so the JDBC driver
internally tries to fit it into a signed int by using the negative values.
Unfortunately that's failing and it's not what the user wants for this
case.  I imagine the user really wants to get a Long back from this.  I'm
going on vacation next week, but when I return, I'll make that happen.
