JavaFX-Anwendung läuft nicht mit Selenium WebDriver

[Adriano10]

public class WebSelenium {
    static String downloadFilePath = "C:\\z";

    public WebSelenium() {

    }

    public void downloadPDFFile(List<String> list) throws InterruptedException {
        //WebDriverManager.chromedriver().setup();
        System.setProperty("webdriver.chrome.driver", "C:/chromedriver.exe");
        ChromeOptions options = new ChromeOptions();
        HashMap<String, Object> chromePrefs = new HashMap<>();
        chromePrefs.put("plugins.always_open_pdf_externally", true);

        chromePrefs.put("download.default_directory", downloadFilePath);
        options.setExperimentalOption("prefs", chromePrefs);
        WebDriver driver = new ChromeDriver(options);

        for (int i = 0; i < list.size(); i++) {
            driver.get("http://asf/nr=" + list.get(i));
            Thread.sleep(5000);
            if (driver.findElement(By.xpath("/html/body/div/div[1]")).getText().equals("Die Suchanfrage wurde erfolgreich verarbeitet")) {
                continue;
            }
            for (int j = 2; j < 6; j++) {
                System.out.println(driver.findElement(By.xpath("/html/body/div[2]/table/tbody/tr[" + j + "]/td/a")).getText());
                if (driver.findElement(By.xpath("/html/body/div[2]/table/tbody/tr[" + j + "]/td/a")).getAccessibleName().length() > 15) {
                    if (driver.findElement(By.xpath("/html/body/div[2]/table/tbody/tr[" + j + "]/td/a")).getAccessibleName().substring(driver.findElement(By.xpath("/html/body/div[2]/table/tbody/tr[" + j + "]/td/a")).getAccessibleName().length() - 3).equals("pdf")) {
                        driver.findElement(By.xpath("/html/body/div[2]/table/tbody/tr[" + j + "]/td/a")).click();
                    }
                }
            }
        }
    }
}

public class Controller implements Initializable {

    public static final String FXML = "/fxml/hello-view.fxml";
    static FileChooser chooser1 = new FileChooser();
    static FileChooser chooser = new FileChooser();
    static DirectoryChooser directoryChooser = new DirectoryChooser();
    private List<String> list = new ArrayList<>();
    private WebSelenium web = new WebSelenium();
    @FXML
    private TextField numbers;

    @Override
    public void initialize(URL url, ResourceBundle resourceBundle) {
        directoryChooser.setInitialDirectory(new File("C:"));
    }

    public void onSearchInvoicnumber(ActionEvent actionEvent) throws InterruptedException {
        String[] array = numbers.getText().split(",");
        for (String number : array){
            list.add(number.replaceAll("'", "").trim());
        }
        if (list != null) {
            this.web.downloadPDFFile(list);
        }
    }

ich bekomme immer diese schreckliche Fehlermeldung
