Thanks for your answer, I'm glad it's safe but I'm still wondering why I've got these messages. The project is a bit large so I can't check it all but the developers insure me that the noticed classes are not used and that's why they are not in the classpath. The jboss-aop.xml file is short and simple and nor references these. Where does these references come from...? I dunno. (^_^) Thanks again, Alexis.
