Aspose Words - Watermark couldn't be set

Hello,
I want to set a watermark on an existing Word document, but for some documents the watermark is not set on the first page. I have no idea who these documents differ from the ones that work, but perhaps you can give me an explanation.
I attached a document where the stamp is not set on the first page, but on the following.
I use the following code, which is copied from your website.

public void setWatermark(Document doc, String wartermarkText) throws Exception
{
    // Create watermark shape
    Shape watermark = new Shape(doc, ShapeType.TEXT_PLAIN_TEXT);
    watermark.getTextPath().setText(wartermarkText);
    watermark.getTextPath().setFontFamily("Arial");
    watermark.setWidth(600);
    watermark.setHeight(100);
    watermark.setRotation(-45);
    // watermark.setBehindText(true);
    // uncomment the following line if you need solid black text
    watermark.getFill().setColor(Color.LIGHT_GRAY);
    watermark.setStrokeColor(Color.LIGHT_GRAY);
    // Set position of watermark
    watermark.setRelativeHorizontalPosition(RelativeHorizontalPosition.PAGE);
    watermark.setRelativeVerticalPosition(RelativeVerticalPosition.PAGE);
    watermark.setWrapType(WrapType.NONE);
    watermark.setVerticalAlignment(VerticalAlignment.CENTER);
    watermark.setHorizontalAlignment(HorizontalAlignment.CENTER);
    // Create new paragraph and append watermark to this paragraph
    Paragraph watermarkPar = new Paragraph(doc);
    watermarkPar.appendChild(watermark);
    for (Section sect: doc.getSections())
    {
        // There could be up to three different headers in each section, since we want
        // the watermark to appear on all pages, insert into all headers.
        insertWatermarkIntoHeader(watermarkPar, sect, HeaderFooterType.HEADER_PRIMARY);
        insertWatermarkIntoHeader(watermarkPar, sect, HeaderFooterType.HEADER_FIRST);
        insertWatermarkIntoHeader(watermarkPar, sect, HeaderFooterType.HEADER_EVEN);
    }
    doc.getViewOptions().setViewType(ViewType.PAGE_LAYOUT);
}

private void insertWatermarkIntoHeader(Paragraph watermarkPara, Section sect, int headerType) throws Exception
{
    HeaderFooter header = sect.getHeadersFooters().getByHeaderFooterType(headerType);
    if (header == null)
    {
        // There is no header of the specified type in the current section, create it.
        header = new HeaderFooter(sect.getDocument(), headerType);
        sect.getHeadersFooters().add(header);
    }
    // Insert a clone of the watermark into the header.
    header.appendChild(watermarkPara.deepClone(true));
}

Hello

Thanks for your inquiry. I cannot reproduce the problem on my side using the latest version of Aspose.Words for Java (4.0.0). You can download this version from here:
https://releases.aspose.com/words/java
Best regards,

Thank you,
the new version solves the problem.
