Yes, that's probably true.
Here's a dirty secret: As you can see from the OpenJDK sources, BigDecimal,
but not BigInteger, has this optimization (see private field
BigDecimal.intCompact). Why BigDecimal but not BigInteger? Because
specjbb2000 uses BigDecimal.
(OTOH, an imperfect metric like specjbb2000 is far better than no metric at
all, for driving competition.)
