> I am try to use the JpegXMPWriter to write xmp values from a Jpeg file. Using JpegImageParser, I can retrieve existing xmp values out the file fine. However, attempting to write back into the file produces an exception.
> byte[] b = null;
> String existingXMP = null;
> String newXMP = null;
> XMPMeta meta = null;
> Document licenseDoc = null;
> JpegImageParser parser = null;       
> JpegXmpRewriter xmpWriter = null;
> ByteArrayOutputStream baos = null;
> b = new byte[is.available()]; // is is a jpeg input stream passed into the function.
> is.read(b);
> is.close(); 
> parser = new JpegImageParser();
> ByteSourceArray bs = new ByteSourceArray(b);
> existingXMP = parser.getXmpXml(bs, null); // works fine, passes back valid xmp from the file
> /* I did have other functionality here to manipulate the xmp which
>    works fine, but I also ran the test without changing the xmp,
>    with the same resulting exception. */
> baos = new ByteArrayOutputStream();            
> xmpWriter.updateXmpXml(bs, baos, existingXMP);  // NullPointerException occurs here.
> b = baos.toByteArray();
> is = new ByteArrayInputStream(b);
> return is;
> Exception produced: 
> java.lang.NullPointerException
