It looks like you have org.jboss.aop.AspectManager included twice in your classpath.
If you are using ant to build do
which will show you the classpath.
AspectManager lives in jboss-aop.jar (which should be used if using jdk 1.4) and jboss-aop-jdk50 (which should be used if using jdk 5.0).
Once I get a look at source SystemClassLoader.java I see the method under question. I'm talking about "install"(line 340).
The first thing you do is loading "org.jboss.aop.AspectXmlLoader" and then "org.jboss.aop.AspectManager". I think it isn't in the right order because AspectXmlLoader himself loads AspectManager. This way you try to load AspectManager twice. This explains why I get scary message.
What can i do?
Kabir, I assume it is 1.3.5m right? And code in head has been fixed? I will test it out myself.
Though, it was depricated it's still very convenient.
Thank you very much.
