Hi, what is your version of "commons-collections.jar"?
The reason why I ask is this snippet of the error message: when resolving method "org.apache.commons.collections.map.LazyMap.decorate(Ljava/util/Map;Lorg/apache/commons/collections/Transformer;)Ljava/util/Map;" the class loader ... of the current class, org/ajax4jsf/application/ComponentsLoaderImpl, and the class loader .. for resolved class, org/apache/commons/collections/map/LazyMap, have different Class objects for the type org/apache/commons/collections/Transformer used in the signature So it seems that "org.apache.commons.collections.Transformer" is referenced in two different versions. Probably this is a requirement of RichFaces. Take a look at their website and find which commons-collections.jar version is required.
