After Fix

    public URL toUrl() throws IllegalArgumentException {
        String address = this.getAddress();
        if (isEmpty(address)) {
            throw new IllegalArgumentException("The address of metadata report is invalid.");
        }
        Map<String, String> map = new HashMap<String, String>();
        URL url = URL.valueOf(address);
        // Issue : https://github.com/apache/dubbo/issues/6491
        // Append the parameters from address
        map.putAll(url.getParameters());
        // Append or overrides the properties as parameters
        appendParameters(map, this);
        // Normalize the parameters
        map.putAll(convert(map, null));
        // put the protocol of URL as the "metadata"
        map.put("metadata", url.getProtocol());
        return new URL("metadata",
            url.getUsername() == null ? this.getUsername() : url.getUsername(),
            url.getPassword() == null ? this.getPassword() : url.getPassword(),
            url.getHost(),
            url.getPort(this.getPort()),
            url.getPath(), map);
