Hi,
We can easily reproduce the problem in Tomcat by just reference the
PortalClusteredSSOSupportValve class in a Servlet Context listener of a web
app, to load it.
I can see that it has been changed in org.apache.catalina.valves.ValveBase
since Tomcat API 7.0 which already defined a final *start()* method from
its indirect parent class org.apache.catalina.util.LifecycleBase
http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/valves/Va...
I confirmed that the problem doesn't happen in JBoss, so I guess this api
part is not consistent between Tomcat and JBossWeb.
In addition, there is no error in compile time as it is using tomcat
catalina version 6.0.29 declared in gatein-dep.
Thanks,
