Spring security taghandler + jsf 2.0 no jboss 6.1

Olá pessoal. Estou tentando usar uma biblioteca e tags feitas para spring secuity (http://code.google.com/p/spring-security-facelets-taglib/). Ao colocar os jars necessários no servidor Jboss 6.1, recebo o seguinte erro

Embora a mensagem seja clara, não estou conseguindo resolver o problema, pois a classe que o log diz estar faltando, está no classpath. O curioso é que no tomcat 7, as coisas funcinam, já no jboss 6.1 não.
