If you implement a VM Profiler such as http://visualvm.java.net/eclipse-launcher.html#installation
and send the profiler output to app1.output then stop app1 and stop tomcat restart tomcat then reference app2 and send the profiler output to app2.output then diff the 2.. can you confirm from the output that app1 is pulling classes from app2/WEB-INF/classes can you confirm from the output that app2 is pulling classes from app1/WEB-INF/classes ?
