[aspectwerkz-user] NoClassDefFoundError on applicatoin init

Hi again all.
Just yesterday we noticed that AspectWerkz throws NoClassDefFoundErrors 
during startup of our web application. The application is run under Caucho 
Resin (2.1.16) and one of the servlets that are run on regular intervals, 
and thus instantiated at application init, contains joinpoints. Therefore, 
during application init, AW throws the error below one time for each 
joinpoint. The thing is that the aspect is still applied when the servet is 
run...

We use AW 2.0 and this problem occurs with offline weaving only. The errors 
can be removed by placing aspectwerkz-2.0.jar in Resins lib (or the system 
classpath), but we do not want to maintain an AW installation on the 
deployment servers.

How can we best track down what is the actual problem?
(Or should we just ignore it, since everything works anyway...?)


Here is the stacktrace:
