I'm trying to add image to new word doc with docx4j

Question

I'm trying to add image to new word document using docx4j. I've taken this code from online and modified it for my program, however I receive a strange error and I'm not sure what is causing it or how to debug it... Here's my code ``` private static void test() { WordprocessingMLPackage wordMLPackage = null; try { wordMLPackage = WordprocessingMLPackage.createPackage(); } catch (InvalidFormatException e1) { // TODO Auto-generated catch block e1.printStackTrace(); javax.swing.JOptionPane.showMessageDialog(panel, "Cannnot create package."); } wordMLPackage.getMainDocumentPart().addStyledParagraphOfText("Title", "Hello Word! 
	" + "Try This!"); byte[] bytes = null; try { bytes = convertImageToByteArray(); } catch (FileNotFoundException e1) { // TODO Auto-generated catch block e1.printStackTrace(); javax.swing.JOptionPane.showMessageDialog(panel, "Image file not found."); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); javax.swing.JOptionPane.showMess…

Here is a simple example, you can take it as a basis.

```
import java.io.*;

import org.docx4j.dml.wordprocessingDrawing.Inline;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;
import org.docx4j.wml.*;
import org.docx4j.openpackaging.parts.WordprocessingML.BinaryPartAbstractImage;

public class Example {
    public static void main(String[] args) throws Exception {
        WordprocessingMLPackage wordprocessingMLPackage = WordprocessingMLPackage.createPackage();
        File file = new File("C://java-duke-logo.jpg" );

InputStream inputStream = new java.io.FileInputStream(file );
        long fileLength = file.length();

byte[] bytes = new byte[(int)fileLength];

int offset = 0;
        int numRead = 0;

while(offset < bytes.length
               && (numRead = inputStream.read(bytes, offset, bytes.length-offset)) >= 0) {
            offset += numRead;
        }

inputStream.close();

String filenameHint = null;
        String altText = null;

int id1 = 0;
        int id2 = 1;

P p = newImage(wordprocessingMLPackage, bytes, filenameHint, altText, id1, id2);

wordprocessingMLPackage.getMainDocumentPart().addObject(p);
        wordprocessingMLPackage.save(new File("C://Example.docx"));
    }

public static P newImage( WordprocessingMLPackage wordMLPackage, byte[] bytes, 
            String filenameHint, String altText, int id1, int id2) throws Exception {
        BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordMLPackage, bytes);
        Inline inline = imagePart.createImageInline( filenameHint, altText, id1, id2);

ObjectFactory factory = new ObjectFactory();

P  p = factory.createP();
        R  run = factory.createR();

p.getParagraphContent().add(run);        
        Drawing drawing = factory.createDrawing();      
        run.getRunContent().add(drawing);       
        drawing.getAnchorOrInline().add(inline);

return p;
    }   
}
```
