The behaviour you describe does not agree with the source for the webdav
servlet (which is the same across all Tomcat versions). The source for
doPropPatch() is:

    protected void doProppatch(HttpServletRequest req,
                               HttpServletResponse resp)
        throws ServletException, IOException {

        if (readOnly) {
            resp.sendError(WebdavStatus.SC_FORBIDDEN);
            return;
        }

        if (isLocked(req)) {
            resp.sendError(WebdavStatus.SC_LOCKED);
            return;
        }

        resp.sendError(HttpServletResponse.SC_NOT_IMPLEMENTED);

    }

Therefore I would never expect to see this work and certainly wouldn't
expect to see a 200. Maybe a configuration issue?

HTH,

Mark
