One solution can be: from this post https://stackoverflow.com/a/5671038/1032167:

     TrustManager trm = new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() {return null;}
        public void checkClientTrusted(X509Certificate[] certs, String authType) {}
        public void checkServerTrusted(X509Certificate[] certs, String authType) {}
    };

    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, new TrustManager[] { trm }, null);
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

There is also post, probably about similar case: JavaFx Webview JDK 8 can not load self signed certificate

How do i know that it was SSL handshake failed

webView.getEngine().getLoadWorker().stateProperty().addListener(
            new ChangeListener<Worker.State>() {
                public void changed(ObservableValue ov, 
                      Worker.State oldState, Worker.State newState) {
            System.out.println(webView.getEngine().getLoadWorker().exceptionProperty());
             ...

also adding add -Djavax.net.debug=all to VMOption shows
