It was my understanding (and this is a somewhat rumour driven
understanding) that the HotSpot VM, actually employs very little of the
"dynamic profiling and adaptive optimization" developed by the Sun Self
project and furthered by the Animorphic HotSpot work. That most of the
improvements in performance are of the more conventional sort. Maybe
others know more which would help dispel/validate this "rumour"?
