'AEM/Jetty and javax.xml.transform.TransformerFactory

We are using the docx4j library to add watermark to the pptx files. Java code below:

public static void main(String[] args) {
try {
   OutputStream object = new FileOutputStream("C:\\test.pptx");
   PresentationMLPackage mlPackage = null;
   BufferedInputStream inputStream = new BufferedInputStream(new URL("https://scholar.harvard.edu/files/torman_personal/files/samplepptx.pptx").openStream(), bufferSize);
   mlPackage = PresentationMLPackage.load(inputStream);

   if(null != mlPackage) {
      MainPresentationPart pp = (MainPresentationPart) mlPackage.getParts().getParts().get(new PartName("/ppt/presentation.xml"));
       for (int i = 0; i < pp.getSlideCount(); i++) {
           SlidePart slidePart = pp.getSlide(i);
           Shape watermark = (Shape) createWatermark("watermark text goes here");
           ((Sld) slidePart.getContents()).getCSld().getSpTree().getSpOrGrpSpOrGraphicFrame().add(watermark);
        }
    }
    if(null != mlPackage) {
       mlPackage.save(outputStream);
    }
} catch (Exception e) {
    System.out.println("Exception inside main  method "+e);
    e.printStackTrace();
}
}

public static Object createWatermark(String watermarkText1) throws JAXBException {
    String OFFX ="offx";
    String OFFY ="offy";
    String EXTCX ="extcx";
    String EXTCY ="extcy";
    HashMap<String, String> mappings = new HashMap<>();
    mappings.put("id", "9999");
    mappings.put("name", "Watermark");
    mappings.put(OFFX, "804291");
    mappings.put(OFFY, "2770742");
    mappings.put(EXTCX, "10533743");
    mappings.put(EXTCY, "1477328");
    mappings.put("watermarkText1", watermarkText1);
    return XmlUtils.unmarshallFromTemplate(sampleWatermark, mappings, Context.jcPML);
}

When I run the above code in eclipse, it is working fine without any issues. Java version: openjdk version "1.8.0_222" classpath file:

The same project if I convert to a maven project and deploy it to AEM (Jetty 9.4), we are getting the below error:

We also tried using docx4j-JAXB-ReferenceImpl instead of docx4j-JAXB-Internal, even then we are getting the same error. Info logs for docx4j package:

Solution 1:[1]

Don't use com.sun.org.apache.xalan.internal.xsltc for XSLT in docx4j.

docx4j 6.1.2 wants to use org.apache.xalan.processor.TransformerFactoryImpl: https://github.com/plutext/docx4j/blob/docx4j-6.1.2/src/main/java/org/docx4j/XmlUtils.java#L100

You have Xalan 2.7.2 there; try removing provided?

And don't mix your docx4j versions (you have 6.1.2 and variously 8.3.2 and 11.3.2 jars). You shouldn't be using 6.1.2 anymore...

In 8.3.2 docx4j uses "org.docx4j.org.apache.xalan.processor.TransformerFactoryImpl": https://github.com/plutext/docx4j/blob/docx4j-parent-8.3.2/docx4j-core/src/main/java/org/docx4j/XmlUtils.java#L102
