Re: [aspectj-users] setting -javaagent:aspectjweaver.jar results inClassCircularityError
|
I have the jar file which contains META-INF/aop-ajc.xml in classpath,
not the aop.xml itself. This jar, which defines no aspects works, in
my test env so I don't think the issue is that there are no aspects.
>From where I am looking, you are a AspectJ guru :-) Any idea how I can
get the attention of someone even more knowledgeable?
