Re: [aspectj-users]"can't determine precedence between two or more pieces of advice that apply to the same join point"

You may read more on a thread on this topic that I had started in
January, based on the difference with AspectWerkz semantics where we
have implemented what you suggest instead of the current AspectJ
semantics.
http://dev.eclipse.org/mhonarc/lists/aspectj-users/msg03412.html
One interesting topic: try to ask yourself what should happen when you
have an around advice defined somewhere in your aspect for the same
join point, and wonder if that 'd be good if ones could not surround a
before advice and the shadow with an around advice f.e.
