javafx natvie bundle: no line number in exception

Question

I've bundled a JavaFx application as a .exe (using ecliplse + Inno), the application is working fine but when an exception is raised I don't get the line number of my code where the exception initiated (it shows "Unknown Source"):

java.io.IOException: The system cannot find the path specified

    at java.io.File.createNewFile(File.java:1012)

I'm redirecting the exception to a TextArea using the below code:

public static void showDialog(Exception e){
    Alert alert = new Alert(AlertType.ERROR);
    alert.setTitle("Exception Dialog");
    alert.setHeaderText("A fatal error occured, please send to the application developper");
    StringWriter sw = new StringWriter();
    PrintWriter pw = new PrintWriter(sw);
    e.printStackTrace(pw);
    String exceptionText = sw.toString();
    Label label = new Label("The exception stacktrace was:");

    TextArea textArea = new TextArea(exceptionText);
    textArea.setEditable(false);
    textArea.setWrapText(true);

    textArea.setMaxWidth(Double.MAX_VALUE);
    textArea.setMaxHeight(Double.MAX_VALUE);
    GridPane.setVgrow(textArea, Priority.ALWAYS);
    GridPane.setHgrow(textArea, Priority.ALWAYS);

    GridPane expContent = new GridPane();
    expContent.setMaxWidth(Double.MAX_VALUE);
    expContent.add(label, 0, 0);
    expContent.add(textArea, 0, 1);

    // Set expandable Exception into the dialog pane.
    alert.getDialogPane().setExpandableContent(expContent);

    alert.showAndWait();
}
