------------------------------------------
Resolution: Fixed
I don't think you are initializing the variable xmpWriter in that code snippet. Hence the NPE?

Using JpegImageParser, I can retrieve existing xmp values out the file
fine. However, attempting to write back into the file produces an
exception.
