The docs refer to createLO which does return long, not create which
returns int.  OID is unsigned int, but since Java doesn't have unsigned
types we need to use long.  This was added relatively recently, as the
original API didn't consider that requirement, so that's why we have a
slight mix of function signatures.  In any case you should be using the
long versions and the int versions should be marked as deprecated.
