         *   everything else takes priority

         * The rules for annotation scanning are not as clear-cut as one might

         * - As per SRV.1.6.2, Tomcat will scan for annotations regardless of
         *   which Servlet spec version is declared in web.xml. The EG has
         *   confirmed this is the expected behaviour.
         * - As per http://java.net/jira/browse/SERVLET_SPEC-36, if the main
         *   web.xml is marked as metadata-complete, JARs are still processed
         *   for SCIs.
         * - If metadata-complete=true and an absolute ordering is specified,
         *   JARs excluded from the ordering are also excluded from the SCI
         *   processing.
         * - If an SCI has a @HandlesType annotation then all classes (except
         *   those in JARs excluded from an absolute ordering) need to be
         *   scanned to check if they match.
