Hi! It is expected that JBoss AOP would create four instances of aspects instead of two. This is true because an interceptor tag declares a new interceptor to JBoss AOP. Whether you have more than one interceptor declaration with the same class is not relevant. Look at the example below: <bind pointcut="execution(static * POJO->*(..))"> | <interceptor class="MethodInterceptor name="interceptor1"/> | </bind> | | <bind pointcut="execution(* POJO$Bar->*(..))"> | <interceptor class="MethodInterceptor" name="interceptor2"/> | </bind> In the xml tags above two different interceptors, with the same class, are declared. Their names are "interceptor1" and "interceptor2". If their names are not defined, JBoss AOP creates a name for those interceptors. So, if you want to use a single interceptor, i.e., to have only one aspect definition generated to represent your interceptor, you should do something like this: <interceptor class="MethodInterceptor name="interceptor1"/> | | <bind pointcut="execution(static * POJO->*(..))"> | <interceptor-ref name="interceptor1"/> | </bind> | | <bind pointcut="execution(* POJO$Bar->*(..))"> | <interceptor-ref name="interceptor1"/> | </bind> However, it looks like JBoss AOP does create two interceptors with the same name when the name attributes are not defined. I will do some investigation before answering this part of your question. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4142966#...
