Hi,

Please use the users forum for user type questions.

It looks like you have org.jboss.aop.AspectManager included twice in your classpath.

If you are using ant to build do

$ant -verbose

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?
Take care

Thanks for your suggestion, it is available in cvs, and will be in the next release :-)

Kabir, I assume it is 1.3.5m right? And code in head has been fixed? I will test it out myself.

[kabirkhan]

Though, it was depricated it's still very convenient.
Thank you very much.
