've been struggling with this problem for a whole day today :( .. I really
wish it is something obvious which you can help me out with ..
so I'm using aspectJ to add some aspect advice to a web application. I'm
doing things quite untidily - in a manual way but I still can;t see what can
be wrong ..
So my pointcut and aspect advice are as follows:
pointcut call_classPreInit():
staticinitialization(ExtensionSystemInitializationContextListener);
after():call_classPreInit() && !cflow(adviceexecution()) {
// do something
}
I'm using eclipse to weave this advice into the original system code. Then I
copy the resultant class directories into my WEB-INF/classes tomcat folder
and restart tomcat.
On trying to load the application, the pointcut described above is reached
and the following exception is thrown ..

I'm finding it very strange that searching for this particular exception on
the web hardly gives any results .. making me think i'm doing something
obviously wrong ... but what??!
Any help would be greatly appreciated!
