I tried it again on a minimal EJB and fresh installation of JBoss 4.2.2, and the same behaviour shows. I report here the files I used, and the installation steps: - Install JBoss 4.2.2 - Enable load time weaving - Put the .ear file in the default/deploy directory - Add pluggable-instrumentor.jar to /bin directory - Add pluggable-instrumentor.jar to classpath and as java option (-javaagent...) - Start JBoss - Run MiniEjbTest.jar, specifying a low delay - Observe in the JBoss output the messages from the interceptor - Run MiniEjbTest.jar, specifying a high delay - Shutdown and restart JBoss - Wait for the timer to fire, observing no message from the interceptor You can find the .EAR and the client .JAR at this URL: http://www.megaupload.com/?d=VBXFXVIK Ask me if you need the source or the netbeans 5.1.1 projects.
