Get the base uri part before the options as they can be non URI valid such as the expression using $ chars and the URI constructor will regard $ as an illegal character and we don't want to enforce end users to to escape the $ for the expression (file language)
    protected String getBaseUri(String uri) {
        String baseUri = uri;
        if (uri.indexOf("?") != -1) {
            baseUri = uri.substring(0, uri.indexOf("?"));
        }
        return baseUri;

Extract additional ftp client configuration options from the parameters map (parameters starting with 'ftpClientConfig.'). To remember these parameters, we set them in the endpoint and we can use them when creating a client.
    protected void extractAndSetFtpClientConfigParameters(Map<StringObjectparametersFtpEndpoint<FTPFileanswer) {
        if (IntrospectionSupport.hasProperties(parameters"ftpClientConfig.")) {
            Map<StringObjectparam = IntrospectionSupport.extractProperties(parameters"ftpClientConfig.");
            answer.setFtpClientConfigParameters(param);
        }
    }
