ClassCastException across modules with org.eclipse.persistence.oxm.XMLBinder

I am trying to read a docx file and replace the author names with a constant string.

This is the code in my main function.

import jakarta.xml.bind.JAXBException;
import org.docx4j.openpackaging.exceptions.Docx4JException;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;
import org.docx4j.openpackaging.parts.WordprocessingML.MainDocumentPart;
import org.docx4j.wml.CTTrackChange;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;


public class App {

    public static void main(String[] args) throws IOException, Docx4JException {
        try {
            // Replace "path/to/your/document.docx" with the actual file path
            String inputFilePath = "src/main/java/shapes.docx";
            String outputFilePath = "output_no_user_info.docx";

            // Load the document
            WordprocessingMLPackage wmlPackage = WordprocessingMLPackage.load(new File(inputFilePath));

            // Remove user information
            removeUserInfo(wmlPackage);

            // Save the modified document
            FileOutputStream fos = new FileOutputStream(outputFilePath);
            wmlPackage.save(fos);
            fos.close();

            System.out.println("User information removed successfully. Saved as: " + outputFilePath);

        } catch (Docx4JException | JAXBException e) {
            e.printStackTrace();
            System.err.println("Error processing the document: " + e.getMessage());
        }
    }

    public static void removeUserInfo(WordprocessingMLPackage wmlPackage) throws Docx4JException, JAXBException {
        MainDocumentPart documentPart = wmlPackage.getMainDocumentPart();
        List<Object> trackedChanges = documentPart.getJAXBNodesViaXPath("//w:ins | //w:del", true);

        for (Object change : trackedChanges) {
            if (change instanceof CTTrackChange) {
                CTTrackChange trackChange = (CTTrackChange) change;
                trackChange.setAuthor("External");
            }
        }
    }
}

The error i'm observing is the below one and it's coming up when there are any shapes in the document. I see CTWordprocessingShape and org.eclipse.persistence.internal.oxm.Root are different classes to be cast and code is breaking in this line of (AbstractMarshalRecordImpl:211).

     Root xr = (Root) originalObject;

Link to code for AbstractMarshalRecordImpl:- https://github.com/eclipse-ee4j/eclipselink/blob/7457271b1829f56746c91197a4d3a643b1da9e60/foundation/org.eclipse.persistence.core/src/main/java/org/eclipse/persistence/internal/oxm/record/AbstractMarshalRecordImpl.java

I'm fairly new to library and please let me know if there is any work around to bypass the issue.

I tried using ReferenceImpl instead of Moxy, ReferenceImpl doesn't cause the below issue.

Exception in thread "main" java.lang.ClassCastException: class org.docx4j.com.microsoft.schemas.office.word.x2010.wordprocessingShape.CTWordprocessingShape cannot be cast to class org.eclipse.persistence.internal.oxm.Root (org.docx4j.com.microsoft.schemas.office.word.x2010.wordprocessingShape.CTWordprocessingShape is in module org.docx4j.openxml_objects of loader 'app'; org.eclipse.persistence.internal.oxm.Root is in module [email protected] of loader 'app')

The problem is @XmlAnyElement(lax = true) in

public class GraphicData implements Child
{
    
    @XmlAnyElement(lax = true)
    protected List<Object> any = new ArrayListDml<Object>(this);

It would work if it instead said:

@XmlElements({
    @XmlElement(name = "wsp", namespace = "http://schemas.microsoft.com/office/word/2010/wordprocessingShape", type = CTWordprocessingShape.class),
})  
protected List<Object> any = new ArrayListDml<Object>(this);

org.docx4j.com.microsoft.schemas.office.word.x2010.wordprocessingShape.CTWordprocessingShape and org.eclipse.persistence.internal.oxm.Root are in unnamed module of loader 'app' suggests a possible JPMS (modularisation) config issue at your end.

Works for me using docx4j-JAXB-MOXy and a module-info.java file which includes:

requires org.docx4j.JAXB_MOXy;

See example at https://github.com/plutext/docx4j/blob/VERSION_11_5_2/docx4j-samples-docx4j/src/main/java/module-info.java

Please note you only need docx4j-JAXB-MOXy; no need to also be adding docx4-core and org.eclipse.persistence.moxy. Also don't mix differing versions (you have 11.4.5 mixed with 11.4.9).

I tested with 11.5.1 on Java 17.

EDIT Doesn't work if org.eclipse.persistence.jaxb.JAXBBinder.updateXML is invoked.
