Sun’s JIT (Just In Time) part of the JDK (Java Development Kit). Code runs first in interpreted mode and is then analyzed and compiled optimized to target platform. It aggressively in-lines frequently used methods, then uses traditional optimisation techniques on the larger code chunks. The HotSpot compiler builds heavily on work done in a PhD thesis by Henry Massalin. The thesis is the mother of all self-modifying code. You not only optimise, you continuously re-optimise.
