Subject: Re: [aspectj-users] Should this work
Aspects.aspectOf(SimpleAroundAspect.class, testC lass) ?


the aspect is singleton (@Aspect without perclause) hence there is no aspect
bound to a particular instance or class. For such aspect you have to use
Aspects.aspectOf(aspectClass) That said you should have a
NoAspectBoundException. I'll file a bug Alex
