AspectWerkz 2.0 Released, Enabling Dynamic AOP

AspectWerkz 2.0 is released today. It support Dynamic AOP, enabling hot deployment and undeployment of aspects at run-time. How wonderful! For us, what this means is, we can dynamically change the behavior of deployed applications without rebooting. I was thinking of using JavaScript to achieve that. Now it's also possible with Java. Only caveat I think is it works for aspects only. How can we do it for a class in general is yet to be seen.
