To PDF/A converted JPG has corrupt XMP-Metdata

[Kaiser, Florian (Extern)]

Hi,

using the infos from
http://svn.apache.org/repos/asf/pdfbox/trunk/examples/src/main/java/org/
apache/pdfbox/examples/pdfa/CreatePDFA.java and
http://java2s.com/Open-Source/Java/PDF/PDFBox-1.4.0/org/apache/pdfbox/ex
amples/pdmodel/ImageToPDF.java.htm I wrote my own program that converts
JPG to PDF/A-1b with PdfBox 2.0.0-SNAPSHOT.

All works fine but according to 3-Heights PDF Validator Online Tool and
the PDF-Validation of PdfBox the PDF is not a valid PDF/A-1b. 
3-Heights tells me

        Validating file "PdfBox-pic23392.pdf" for conformance level
pdfa-1b
        XML line 1:1: Start tag expected, '<' not found.
        The document does not conform to the requested standard.
        The document's meta data is either missing or inconsistent or
corrupt.

and PdfBox-Validation

        java.lang.AssertionError: File is not a valid PDF/A-1b: 
        Error on MetaData, Failed to parse [7.1]

The source code of my program is

            }

Am I doing something wrong or is this a bug?

Thanks for the help.
