Ok Kabir, I have downloaded the new example classes fixed from cvs and I see that the TestCase you done, works well. But if you change the code of jboss-aop.xml file from: <interceptor class="org.jboss.test.aop.regression.jbaop336callnpe.LogInterceptor"/> | <bind pointcut="call(org.jboss.test.aop.regression.jbaop336callnpe.Log->new(java.lang.String))"> | <interceptor-ref name="org.jboss.test.aop.regression.jbaop336callnpe.LogInterceptor"/> | </bind> to: <interceptor class="org.jboss.test.aop.regression.jbaop336callnpe.LogInterceptor"/> | <bind pointcut="call(org.jboss.test.aop.regression.jbaop336callnpe.Log->new(..))"> | <interceptor-ref name="org.jboss.test.aop.regression.jbaop336callnpe.LogInterceptor"/> | </bind> the java NullPointerException in _getInstanceAdvisor() will occour!! Could you fix this problem? Otherwise it's impossible to use call expression pointcuts..... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3997520#...
