I assume you're using G 1.1.1 for a reason. Have you tried 2.1.4?

You must be doing more than simply creating an aop.xml file.  
Otherwise, how is AspectJ getting loaded/triggered to read the  
configuration file?

Maybe others who have used it. I've never tried it. But interested to  
see it running. Even more interested to see it on G 2.1.4 :-P, but  
happy to help with 1.1.1, also...

Prolly best to follow up on our user@ list...
