The library hippo-ecm-addon-reviewed-action-repository-2.12.06.jar is missing.
This jar includes the file hippostdpubwf.cnd what the Upgrader12a class needs.

Line 111 in Upgrader12a.java:
context.registerVisitor(new UpdaterItemVisitor.NamespaceVisitor(context,"hippostdpubwf", "-",new InputStreamReader(getClass().getClassLoader().getResourceAsStream("hippostdpubwf.cnd"))));

Is it possible to include more debug logging or throw a more readable error message in the Upgrader12a.java so it's easier to find out if the class loader is missing a file?
