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

[Nishanth-GH]

I am trying to read a docx file and replace the author names with a constant string.
The library i'm using to manipulate docx files is Docx4j-Moxy. This library uses org.eclipse.persistence:org.eclipse.persistence.moxy.

When there is any shape element in the docx file, the below error is coming up.

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 and org.eclipse.persistence.internal.oxm.Root are in unnamed

In AbstractMarshalRecordImpl.java:211 we are casting org.docx4j.com.microsoft.schemas.office.word.x2010.wordprocessingShape.CTWordprocessingShape to org.eclipse.persistence.internal.oxm.Root which is causing the exception.

I have tried the alternative docx4j-JAXB-ReferenceImpl instead of docx4j-JAXB-MOXy which doesn't cause the issue. ReferenceImpl uses org.glassfish.jaxb.runtime.v2.runtime.BinderImpl instead of JAXBBinder.

I have uploaded a light weight maven project where issue could be replicated.(It also has input .docx file that causes the issue)

Per https://stackoverflow.com/a/79370090/1031689 this problem is triggered by annotation @XmlAnyElement(lax = true)

This is in the docx4j class:

public class GraphicData
{

@XmlAnyElement(lax = true)
protected List<Object> any = new ArrayListDml<Object>(this);

It would work if it instead said, for example:

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