java.lang.IllegalAccessError when usind controlsfx with JavaFX in Java 11

See original GitHub issue

I am trying to use org.controlsfx.control.textfield.AutoCompletionBinding along with JavaFX in Java 11. This is my maven dependency:

<dependency>
        <groupId>org.controlsfx</groupId>
        <artifactId>controlsfx</artifactId>
        <version>11.0.1</version>
</dependency>

And my module-info.java:

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

    requires org.controlsfx.controls;
}

Exception in thread "JavaFX Application Thread" java.lang.IllegalAccessError: class org.controlsfx.control.textfield.AutoCompletionBinding (in module org.controlsfx.controls) cannot access class com.sun.javafx.event.EventHandlerManager (in module javafx.base) because module javafx.base does not export com.sun.javafx.event to module org.controlsfx.controls
