It sure is.  I once came across an attempt at copy protection scheme
with license keys done in Java.  I reverse engineered it by accident
while looking for something else.

But you can't have pointers to the non-object versions.

Ugh.

This becomes especially annoying when you need 32 bits unsigned
space.  Going up to 64 bits slows things down on 32-bit hardware.
