I think it's this bit from jboss-web-cluster.sar/jboss-web-cluster.aop/META-INF/jboss-aop.xml that is causing you trouble:


  |    <!-- Make any POJO with a JDK5 PojoCacheable annotation as a Subject/Observerable -->
  |    <bind pointcut="set(* @org.jboss.cache.aop.annotation.PojoCacheable->*)">
  |       <interceptor class="org.jboss.aspects.patterns.observable.SubjectInterceptor"/>
  |    </bind>
  | 
  |    <introduction class="@org.jboss.cache.aop.annotation.PojoCacheable">
  |       <mixin>
  |          <interfaces>org.jboss.aspects.patterns.observable.Subject</interfaces>
  |          <class>org.jboss.aspects.patterns.observable.SubjectImpl</class>
  |          <construction>new org.jboss.aspects.patterns.observable.SubjectImpl(this)</construction>
  |       </mixin>
  |    </introduction>
  | 

The latter causes the AspectManager to insert a SubjectInterceptor when you deploy your class.  But when you did your aopc, your jboss-aop.xml didn't include the "introduction" element.  So your class doesn't implement the Subject interface and you get a CCE when the SubjectInterceptor gets invoked.

Two possible solutions:

1) Add the "introduction" element above to your jboss-aop.xml and run aopc again.

2) If you don't use FIELD granularity web session replication, remove the jboss-web-cluster.sar/jboss-web-cluster.aop file.
