I'm new to modularized java 16 projects as well as using the maven build system whilst trying to implement the program using IntelliJ, JAVAFX and APACHE POI-OOXML.

For simplicity, I am implementing a button's event handler that instantiates a class that is responsible for using Apache:
[ControllerCode](https://i.stack.imgur.com/ABnIL.png)

The problem then happens here: [line 24 of this code](https://i.stack.imgur.com/LbvXS.png)

Here is the stack trace:

I am completely new to all of these but I feel as though this line from the stack trace above is the culprit:

```
Caused by: java.lang.IllegalAccessError: superclass access check failed: class org.apache.poi.openxml4j.util.ZipSecureFile (in module org.apache.poi.ooxml) cannot access class org.apache.commons.compress.archivers.zip.ZipFile (in unnamed module @0x2db197a2) because module org.apache.poi.ooxml does not read unnamed module @0x2db197a2

```

Here is the module-info:

```
module com.example.demo3 {
    requires javafx.controls;
    requires javafx.fxml;
    requires org.apache.poi.ooxml;

    opens com.example.demo3 to javafx.fxml;

    exports com.example.demo3;
} 

```

My maven dependencies:

```
<dependencies>
    <dependency>
        <groupId>org.openjfx</groupId>
        <artifactId>javafx-controls</artifactId>
        <version>16</version>
    </dependency>

        <artifactId>poi-ooxml</artifactId>

    </dependency>
</dependencies> 

```

I would appreciate all help that I can get :)
