Thanks, Kabir, for the suggestion. But, I am currently running with jboss-aop 1.5.2 GA and JDK 1.4.2_12. I have this same issue. Here's a snippet of my jboss-aop.xml: | <bind pointcut="execution(public * $instanceof{com.hp.d2d.pal.hibernate.AbstractHPAL}->*(..))"> | <interceptor class="com.hp.d2d.aop.MethodTimerInterceptor"/> | </bind> | <bind pointcut="call(* com.hp.d2d.pal.BackupPolicyPAL->*(..))"> | <interceptor class="com.hp.d2d.aop.TracerInterceptor"/> | </bind> | I basically want to time all the methods of the subclasses of AbstractHPAL, some of which implement the BackupPolicyPAL interface.
