Module camel-rss exposes com.sun.syndication

[tdiesler]

Module org.apache.camel.component.rss incorrectly exports com.sun.syndication packages. These should be an implementation detail of camel-rss

This is because of rome PropertiesLoader

    public static PropertiesLoader getPropertiesLoader() {
        synchronized(PropertiesLoader.class) {
            PropertiesLoader loader = (PropertiesLoader)
                clMap.get(Thread.currentThread().getContextClassLoader());
            if (loader == null) {
                try {
                    loader = new PropertiesLoader(MASTER_PLUGIN_FILE, EXTRA_PLUGIN_FILE);
                    clMap.put(Thread.currentThread().getContextClassLoader(), loader);
                }
                catch (IOException ex) {
                    throw new RuntimeException(ex);
                }
            }
            return loader;
        }
    }
