This seams due to a conflict between two versions of ReflectiveServiceLayer: please note it's not a ClassNotFound but a NoClassDefFound which is often related to a conflict. i still didn't solve my problem but there is clearly this class twice: (try with Ctrl + Shift + T in eclipse): it's both in gwt-servlet and in gwt-user
For me the issue happens on some deployements but not in others (with the same dependencies), so this is probably due to the order in which the jvm reads the classes...
