Hiya, Given there's no jspwiki code in that stack trace, my guess would be either a jspwiki serialization file has been serialized with one jdk and it's been tried to be deserialized with another, or something similar with the JSPs under Tomcat's work directory?
Maybe clearing tomcat's and/or jspwiki's work directory would make that exception disappear?
