Thanks for your quick responses.
I'm using JBoss 4.2.3 and jboss-aop 1.5.6. Unfortunately I cannot upgrade the AOP version to >= 2.0.0 :(
I decompiled the AspectManager and the instance() method looks like this:
public static synchronized AspectManager instance()
{
return instance(Thread.currentThread().getContextClassLoader());
}
As I do not have any influence on my runtime environment I can only patch the ClassicInstrumentor at compile time and replace the following line
addStaticField(clazz, "aop$classAdvisor$aop", HELPER_CLASS_NAME, CtField.Initializer.byExpr(ASPECT_MANAGER_CLASS_NAME + ".instance().getAdvisor(java.lang.Class#forName(\"" + clazz.getName() + "\"))"));
by something else e.g.
addStaticField(clazz, "aop$classAdvisor$aop", HELPER_CLASS_NAME, CtField.Initializer.byExpr(ASPECT_MANAGER_CLASS_NAME + ".instance(java.lang.Class#forName(\"" + clazz.getName() + "\"))".getClassLoader()).getAdvisor(java.lang.Class#forName(\"" + clazz.getName() + "\"))"));
Maybe the classloader of the advised class is the correct one.
