java.lang.IllegalAccessError with JFoenix and JavaFX in Java 11

Question

I am trying to use com.jfoenix.controls.JFXChipView along with JavaFX in Java 11. This is my maven dependency:

    <dependency>
        <groupId>com.jfoenix</groupId>
        <artifactId>jfoenix</artifactId>
        <version>9.0.9</version>
    </dependency>

I am also using com.jfoenix.controls.JFXCheckBox in another module which works well, but when I am trying to open a module which includes the ChipView, I get the following error:

Exception in thread "JavaFX Application Thread" java.lang.IllegalAccessError: class com.jfoenix.controls.JFXAutoCompletePopup (in module com.jfoenix) cannot access class com.sun.javafx.stage.PopupWindowHelper (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.stage to module com.jfoenix

My module-info.java looks like this:

open module gui {
    requires javafx.controls;
    requires javafx.graphics;
    requires javafx.fxml;
    requires javafx.base;

    requires com.jfoenix;
    requires static lombok;
    requires spring.context;
    requires java.desktop;
    requires core_entity;
    requires util;
    requires spring.boot.autoconfigure;
    requires spring.boot;
    requires controlsfx;

    requires com.fasterxml.classmate;
