Given that there is a precedence in this file:


        p = props.getProperty("jdk.net.URLClassPath.showIgnoredClassPathEntries");
        DEBUG_CP_URL_CHECK = p != null ? p.equals("true") || p.isEmpty() : false;


I would tend to let the new property follow the same pattern, especially since it's temporary.
