False negative with 2503.pdf file of issue PDFBOX-2503

Using the code of the CookBook for PDF/A validation (1.8.10) :

• with the 2503.pdf as entry file
• and only replacing the code "parser.parse()" with "parser.parse(Format.PDF_A1B)",

result.isValid() is false with 1.8.10, 2.0.0-RC1 and 2.0.0-RC2 versions of pdfbox and preflight. The error displayed is : "7.2 : Error on MetaData, CreationDate present in the document catalog dictionary doesn't match with XMP information"

Note : With same file and version 1.8.8, I get as expected a result.isValid() true and, with version 1.8.7, I actually obtain the "7.2 : Error on MetaData, Producer present in the document catalog dictionary doesn't match with XMP information" error message given in the issue PDFBOX-2503.
