Yes I inherited that choice, and I definitely noticed the problems,  which is why I consider it's usage of AOP to be a failed experiment. Although we did tell people who cared about performance to use offline compilation when running under the AS. We also had all kinds of usability issues with it (most of problems reported where configuration errors, weaving issues, or stub compatibility problems). 

The future replacement of PojoCache will take a saner JPA-like approach. BTW I don't mean to criticize JBossAOP, it's a good implementation of AOP. I just think we are using it solve problems that have way simpler and way faster solutions.
