Depressed for a long time, finally settled, the answer is in these English.

If you encounter this issue with 4.0.5.GA, until the update is available, do the following:

1. If you don't use http session clustering, you can remove tc5-cluster.aop from your

Deploy directory and use your own jboss-aop.xml. That should work.

2. If you do, you will need to include tc5-cluster.aop in your classpath when

Instrumenting the classes. Furthermore, you will need jboss-aop-aspect.jar

(for aop aspects) in your classpath as well during compilation.
