In the present day at the end of 2018 nothing of these solutions works with JavaFX of JDK 1.8. So I've working on a simple solution. You can copy this method in and utility class:

public static boolean hideArrow(TitledPane pane) {
    Node arrowButton = pane.lookup(".arrow-button");
    if (arrowButton == null) {
        return false;
    }
    // I don't know how with this the arrow space disappears...., but it does
    arrowButton.setStyle("-fx-background-color: black;");
    Parent titleRegion = arrowButton.getParent();
    titleRegion.addEventFilter(MouseEvent.ANY, MouseEvent::consume);
    titleRegion.setCursor(Cursor.DEFAULT);
    ((StackPane) titleRegion).getChildren().remove(arrowButton);
    return true;
}
