[aspectj-users] Re: java.lang.ArrayIndexOutOfBoundsException Error
Hi, Ramnivas,
 
I think you get my point. But in what situation aspectJ will not give Args and throws the ArrayIndexOutOfBoundsException? Thanks!!

Thank you both! I think your solutions are the same per se. One is elegant
and the other is compact. I've resolved my problem. Thank you!
By the way, my god, it's you Ramnivas replied my email! I read your book two
years ago, but didn't practice much at that time, so have forgotten most ot
them. Your reply is a big encouragement to me!

Terry,

I am quite sure if I understand the question. However, you shouldn't have to
do anything special to have arguments available to the ProceedingJoinPoint
object in an around advice; its getArgs() method will give you an array of
objects at the advised join point.
