Yes, that was just a way to reproduce the issue.
About the real usecase that Hoang has reported, it is a Spring 3.x web app. For a certain
reason, Spring auto scans all Valves which causes the issue.

if I understand the usecase. Why you need to access PortalClusteredSSOSupportValve from
some Servlet Context listener on Tomcat? Thing is that PortalClusteredSSOSupportValve is
meant to be used only in JBoss because it uses JBoss specific clustered SSO valve. It does
not makes sense to use it in Tomcat.

solve your issue, because than you won't be able to compile your listener anyway
because PortalClusteredSSOSupportValve won't be available. But maybe I still don't
uderstand the usecase...
