[aspectj-dev] Re: reflective calls

[Alexandre Vasseur <avasseur@xxxxxxxxx>]

The question may then be: if someone implements an AspectJ weaver (as
the trend starts to surface thru ABC and JRockit) would there be a
need for an option to turn on/off this reflective call matching.
Note that as I said some aspect can be added to handle that as well in
weavers that don't have the capability to do this kind of matching.

The same question would be raised if f.e. one would ask for an AspectJ
TCK, or more generally with "what is the call pointcut exact behavior"
(no matter the language beehind - reflection is existing in .Net if I
remember).
