That's how we did it in JRuby. Our Fixnums are mostly
like other objects, with the exception that they
aren't stored in the ObjectSpace and that the
instances for 0-255 are cached.

In Java it is very hard to use a "native" integer
representation like Matz' Ruby does, so we'll probably
never see that on the Java platform. Parrot seems to
be much better in this aspect.
