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
