My thought was to change the second part of that method to this:
{code}

        Set<COSDictionary> widgetDictionarySet = new HashSet<>();
        for (PDField field : fields)
        {
            List<PDAnnotationWidget> widgets = field.getWidgets();
            for (PDAnnotationWidget widget : widgets)
            {
                widgetDictionarySet.add(widget.getCOSObject());
            }
        }

        for (PDPage page : document.getPages())
        {
            for (PDAnnotation annotation : page.getAnnotations())
            {
                if (widgetDictionarySet.contains(annotation.getCOSObject()))
                {
                    fillPagesAnnotationMap(pagesAnnotationsMap, page, (PDAnnotationWidget) annotation);
                }
            }
        }
{code}
It seems to work but now the annotations are direct objects, and the file can't be opened with Adobe Reader.

Update: it also fails a flatten test. This is getting tricky.

>          Issue Type: Bug
>          Components: AcroForm
>    Affects Versions: 2.0.24

> {code}
>         PDAcroForm acroForm = doc.getDocumentCatalog().getAcroForm();
>         List<PDField> list = new ArrayList<>();
>         list.add(acroForm.getField("VN_NAME"));
>         acroForm.flatten(list, true); 
> {code}
> The code from buildPagesWidgetsMap that is run when there are widgets with missing page references does not consider the field list. So all widgets end up in the map instead of only those we care about.
