Hey, I'm a developer from DrFTPD, a Java FTP Daemon, and I'm planning to use JBoss AOP in a part of the project. Our current code depends heavily on JPF (Java Plugin Framework). Quoting from JPF's site: "The plug-in architecture used by Eclipse was taken as the basic model for JPF in early 2004.". This frameworks provides an easy way of adding extensions, creating a complex plugin hierarchy with dependencies, on-the-fly reloading of classes, etc... But in order to manage all this nice stuff it relies heavilly on its own ClassLoaders (lots are use, creating a complex ClassLoaders graph). Well, enough of explanations, let's go to the real fun :P Running an example that is distributed with JBoss AOP 2.0 CR8, I get the following output: | DEBUG main org.jboss.aop.instrument.InstrumentorFactory - Passed in instrumentor: null | DEBUG main org.jboss.aop.instrument.InstrumentorFactory - Defaulting instrumentor to: org.jboss.aop.instrument.GeneratedAdvisorInstrumentor | DEBUG main org.jboss.aop.AdvisorFactory - Passed in advisor: null | DEBUG main org.jboss.aop.AdvisorFactory - [debug] Defaulting advisor to: org.jboss.aop.ClassAdvisor | DEBUG main org.jboss.aop.Deployment - jboss.aop.class.path is NULL | DEBUG main org.jboss.aop.Deployment - jboss.aop.search.classpath: 'null' true | DEBUG main org.jboss.aop.Deployment - jboss.aop.path: jboss-aop.xml | DEBUG main org.jboss.aop.Deployment - jboss.aop.path[0]: jboss-aop.xml | DEBUG main org.jboss.aop.Deployment - deploying file:/home/flavio/drftpd/workspace/TestAOP/jboss-aop.xml | DEBUG main org.jboss.aop.AspectXmlLoader - AspectXMLLoader using managerorg.jboss.aop.AspectManager@126804e | DEBUG main org.jboss.aop.instrument.Instrumentor - trying to transform test.Driver | DEBUG main org.jboss.aop.instrument.CallerTransformer - There are no caller pointcuts!

But when I try to run DrFTPD using the same parameters I used to run the example I only get the following output: | [aop-debug] org.jboss.aop.instrument.InstrumentorFactory Passed in instrumentor: null | [aop-debug] org.jboss.aop.instrument.InstrumentorFactory Defaulting instrumentor to: org.jboss.aop.instrument.GeneratedAdvisorInstrumentor | [aop-debug] org.jboss.aop.AdvisorFactory Passed in advisor: null | [aop-debug] org.jboss.aop.AdvisorFactory [debug] Defaulting advisor to: org.jboss.aop.ClassAdvisor | [aop-debug] org.jboss.aop.Deployment jboss.aop.class.path is NULL | [aop-debug] org.jboss.aop.Deployment jboss.aop.search.classpath: 'null' true | [aop-debug] org.jboss.aop.Deployment jboss.aop.path: conf/aop | [aop-debug] org.jboss.aop.Deployment jboss.aop.path[0]: conf/aop | [aop-debug] org.jboss.aop.Deployment deploying file:/home/flavio/drftpd/trunk/conf/aop/lucene-aop.xml | [aop-debug] org.jboss.aop.AspectXmlLoader AspectXMLLoader using managerorg.jboss.aop.AspectManager@503429 | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.java.plugin.boot.ApplicationInitializer | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.java.plugin.boot.SplashHandler | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.java.plugin.boot.BootErrorHandler | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.java.plugin.boot.PluginsCollector | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy warning, isFrozen: org.apache.log4j.Category [class path: sun.misc.Launcher$AppClassLoader@17182c1:] - dcl sun.misc.Launcher$AppClassLoader@17182c1 | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.apache.log4j.spi.AppenderAttachable | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.apache.commons.logging.Log | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.apache.log4j.spi.LoggerRepository | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.apache.log4j.spi.RepositorySelector | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.apache.log4j.spi.RendererSupport | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.apache.log4j.spi.LoggerFactory | [aop-debug] org.jboss.aop.SuperClassesFirstWeavingStrategy cannot compile, isInterface: org.apache.log4j.or.ObjectRenderer | That's not all the output, but the rest is pretty much the same.

I'm willing to provide anymore info you need in order to trace my problem.
