Could it be the cause?
This is very likely the cause. Typically AspectJ will look for the aop.xml
via a getResources("META-INF/aop.xml") call on the classloader. If the
classloader doesn't implement getResources in a good way, the file won't be
found. As an alternative (as I look at the AJ source code) you might be
able to specify a file path for it:
-Dorg.aspectj.weaver.loadtime.configuration=file:/path/to/my/aop.xml
