Re: [Springframework-developer] AOP changes

[Rod J. <rod...@in...>]

It shouldn't have much impact on apps. Just simple class name substitution,
from whatever to DefaultPointcutAdvisor or to RegexpMethodPointcutAdvisor.

I've also simplified the implementation of the aop.adapter package following
the earlier changes. This doesn't affect applications at all. Indeed, I
didn't change the test suite at all.

Regards,
Rod
