Alexis, These references come from code that JBoss AOP is parsing in order to peform weaving. Whenever JBoss AOP finds a class in the source classpath (the one that you set, telling JBoss AOP where to find the classes that must be weaved), JBoss AOP needs to check on every reference to another class, to see if that reference (it could be a call, the type of a field, etc) is a joinpoint that must be weaved. When JBoss AOP doesn't find that referenced class in the classpath, it will print a message warning you of this. So, there are classes in the source classpath that reference the classes mentioned in the warning messages.
