It's been awhile since I blogged, so I thought I'd touch base with people to let them know what's been going on. Azul Systems has been hard at work improving our JVM. This is a bigger statement than it sounds - there are not many groups that have a large enough 'quorum' of JVM engineers to do large-scale changes to the HotSpot JVM. Azul has nearly a dozen engineers doing core HotSpot work (not counting JDK work or QA folks - counting only core JVM engineers)! We've been doing large-scale changes to HotSpot for nearly 8 years now.
