The <a4j:support> has been replaced by <a4j:ajax>. Update all your code accordingly. The stacktrace suggests that one of the backing beans has a HtmlAjaxSupport property. You need to remove it.
Read the RichFaces 3.3.x to 4.x migration guide to have an overview of all necessary changes which you need to make to an existing RichFaces 3.3.x webapp while migrating it to RichFaces 4.x. It's really not a matter of just replacing the JARs.
