That occurred to me, but since I know nothing about how the JVM might do 
that, I didn't speculate.

Interesting.  I mostly just increment Integers by one.  If the addresses 
of pre-allocated Integers (<127) are all stored sequentially, then 
that's equivalent to adding a constant offset to each address, about the 
same overhead as just adding 1.  Hmmm, that's 100% speculation, but a 
cool optimization if they do it that way.
