Instead of WatermarkArtifact, you can still use TextStamp in order to add watermark like below:

Document doc = new Document(dataDir + "Sample-pdf.pdf");

// Create a formatted text
com.aspose.pdf.facades.FormattedText formattedText = new com.aspose.pdf.facades.FormattedText("Confidential Document", java.awt.Color.RED, com.aspose.pdf.facades.FontStyle.Courier, com.aspose.pdf.facades.EncodingType.Identity_h, true, 40.0F);

// Create watermark artifact and set its properties
TextStamp artifact = new TextStamp(formattedText);
artifact.setHorizontalAlignment(HorizontalAlignment.Center);
artifact.setVerticalAlignment(VerticalAlignment.Center);
artifact.setRotateAngle(25);
artifact.setOpacity(0.5);
artifact.setBackground(false);

java.text.DateFormat dateFormat = new java.text.SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
String fdate = dateFormat.format(date);

TextStamp textStamp = new TextStamp(fdate);

// Add watermark to all pages of the PDF
PageCollection pdfPageCollection = doc.getPages();
for (Page pdfPage : pdfPageCollection) {
    pdfPage.addStamp(artifact);
}

// Set properties for the date stamp
textStamp.setBottomMargin(10);
textStamp.setHorizontalAlignment(HorizontalAlignment.Center);
textStamp.setVerticalAlignment(VerticalAlignment.Bottom);

// Add footer with the current date on all pages
for (Page page : pdfPageCollection) {
    page.addStamp(textStamp);
}

doc.save(dataDir + "watermarked.pdf");
