NullPointerException when converting a sample docx to pdf file

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Code:
public class Docx2Pdf {

    public static void main(String[] args) throws IOException {
        long start = System.currentTimeMillis();

        InputStream is = new FileInputStream(new File("/Users/chengliang/docs/unmarshallFromTemplateExample.docx"));
        XWPFDocument document = new XWPFDocument(is);
        PdfOptions options = PdfOptions.create();
        OutputStream out = new FileOutputStream(new File("/Users/chengliang/out/test.pdf"));
        PdfConverter.getInstance().convert(document, out, options);

        System.err.println("Generate pdf with " + (System.currentTimeMillis() - start) + "ms");
    }
}
2. I was using 
      <dependency>
          <groupId>org.apache.pdfbox</groupId>
          <artifactId>pdfbox</artifactId>
        <version>1.8.3</version>
      </dependency>

      <dependency>
          <groupId>fr.opensagres.xdocreport</groupId>
          <artifactId>fr.opensagres.xdocreport.document.docx</artifactId>
          <version>1.0.3</version>
      </dependency>

      <dependency>
          <groupId>fr.opensagres.xdocreport</groupId>
          <artifactId>fr.opensagres.xdocreport.template.freemarker</artifactId>
          <version>1.0.3</version>
      </dependency>

      <dependency>
        <groupId>fr.opensagres.xdocreport</groupId>
        <artifactId>fr.opensagres.xdocreport.converter.docx.xwpf</artifactId>
        <version>1.0.3</version>
      </dependency>

What is the expected output? What do you see instead?

Expecting a pdf file to be generated. I saw

Your docx seems very strange. It doesn't contains w:sectPr in your 
word/document.xml. This sectPr gives the width/height of the page. Without that 
I don't know how to retrieve it?

Have you used MS Word to create this word? If yes, which version do you use?

Thanks for taking a look.

I was using Docx4j and the word file I used comes from one example there. I 
used my Mac MS word 2011 to save it again and now xdocreport can process it.

Can you please let me know how you debug it? Otherwise please feel free to 
close this bug .

It's the first time that I have this case (word/doucment.xml doesn't contains 
w:sectPr) and  as I have explained you, I don't know which width/height I must 
use. I close this issue, but If some people are the same problem, I will study 
it more how to fix it. But if you use MS Word you should not have this problem.

I have noticed too that you use ${colour} in your docx without mergefield. You 
will have trouble if you don't use mergefield to merge your docx with java 
context. I suggest you to read

docx file to pdf i am getting exception.
2) Create docx file using MS Office, i am not getting any exception and pdf 
conversion is successful..
