Subject [jira] Created: (SANSELAN-19) JpegXMPWriter throws NullPointerException

JpegXMPWriter throws NullPointerException
-----------------------------------------

                 Key: SANSELAN-19
                 URL: https://issues.apache.org/jira/browse/SANSELAN-19
             Project: Sanselan
          Issue Type: Bug
         Environment: Windows XP, JDK 1.5
            Reporter: Kelly Boettcher


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;
