Error getting pdf from docx using POI

I want to convert docx to pdf with apache poi, docx is generated correctly with docx4j. The conversion works with a simple document, but when I want to convert a more stylized document, the POI throws an exception:

org.apache.xmlbeans.impl.values.XmlValueOutOfRangeException: union value '0000FF "> http://schemas.openxmlformats.org/wordprocessingml/2006/main' 15:09:20 org.apache.poi.xwpf.converter.core .XWPFConverterException: org.apache.xmlbeans.impl.values.XmlValueOutOfRangeException: union value '0000FF "> http://schemas.openxmlformats.org/wordprocessingml/2006/home' at org.apache.poi.xwpf.converter.pdf. PdfConverter.doConvert (PdfConverter.java:70) ~ [org.apache.poi.xwpf.converter.pdf-1.0.6.jar: 1.0.6]

There is a reason for this exception:

<w:r>
    <w:rPr>
        <w:rFonts w:ascii="Arial" w:hAnsi="Arial" w:cs="Arial"/>
        <w:color w:val="0000FF"><span style="background-color: rgb(51, 153, 102);"><span style="background-color: rgb(255, 0, 0);"><font color="99CC00"/>
        <w:sz w:val="20"/>
        <w:szCs w:val="20"/>
        <w:highlight w:val="red"/>
    </w:rPr>
    <w:t xml:space="preserve">Juillet-Aout</w:t>
</w:r>

My document screen

And this is my code:

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.OutputStream;


import org.apache.poi.xwpf.usermodel.XWPFDocument;

import fr.opensagres.poi.xwpf.converter.pdf.PdfConverter;
import fr.opensagres.poi.xwpf.converter.pdf.PdfOptions;

public class ConvertDocxPdf
{

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

        try
        {
            // 1) Load docx with POI XWPFDocument
            InputStream source = new FileInputStream("test.docx");
            XWPFDocument document = new XWPFDocument(source);

            // 2) Convert POI XWPFDocument 2 PDF with iText
            File outFile = new File("result.pdf" );
            outFile.getParentFile().mkdirs();

            OutputStream out = new FileOutputStream( outFile );
            PdfOptions options = null;// PDFViaITextOptions.create().fontEncoding( "windows-1250" );
            PdfConverter.getInstance().convert( document, out, options );
        }
        catch ( Throwable e )
        {
            e.printStackTrace();
        }

        System.out.println( "Generate DocxStructures.pdf with " + ( System.currentTimeMillis() - startTime ) + " ms." );
    }
}

And this is the XML line that causes the problem:

<w:r>
    <w:rPr>
        <w:rFonts w:ascii="Arial" w:hAnsi="Arial" w:cs="Arial"/>
        <w:color w:val="0000FF"><span style="background-color: rgb(51, 153, 102);"><span style="background-color: rgb(255, 0, 0);"><font color="99CC00"/> //<-- That line
        <w:sz w:val="20"/>
        <w:szCs w:val="20"/>
        <w:highlight w:val="red"/>
    </w:rPr>
    <w:t xml:space="preserve">Juillet-Aout </w:t>
</w:r>
