Tomcat 7 failed to restart after richfaces & JSF migration - jsf

Question

I'm migrating Richfaces version from 3.3.3 to 4.3.5 and JSF from 1.2
to 2.2.6 and I have made the following changes:
Removed the below jars: jsf-api.jar jsf-facelets.jar jsf-impl.jar richfaces-api-3.3.3.Final.jar richfaces-impl-3.3.3.Final.jar
richfaces-ui-3.3.3.Final.jar
Added the below jars: cssparser-0.9.5.jar guava-10.0.1.jar richfaces-components-api-4.3.5.Final.jar
richfaces-components-ui-4.3.5.Final.jar
richfaces-core-api-4.3.5.Final.jar richfaces-core-impl-4.3.5.Final.jar
sac-1.3.jar jsf-impl-2.2.6.jar jsf-api-2.2.6.jar
And made changes in: 1) faces-config.xml (changes version from 1.2
to 2.2:
<?xml version="1.0" encoding="UTF-8"?<faces-config
version="2.2" xmlns="http://java.sun.com/xml/ns/javaee"

Changes version from 2.5 to 3.1
3) I'm running with JDK 7
