Convert PDF to PDF/A in Java - Output file is not PDFA conformant


We use licenced Aspose.Total product for Java latest versions (cells, words, pdf) on Linux server Ubuntu 18.04.4 LTS.

The problem happens while converting files from pdf to pdfa-3b.
No errors while convertion - but the resulted document does not pass pdfa-3b validation.
Files are attached - input document to convert, resulted document, conversion log and validation failure in https://www.pdf-online.com/osa/validate.aspx and https://demo.verapdf.org/.

Conversion options we use:
pdfDocument = new Document(“problemPdf.pdf”);
conversionOptions = new PdfFormatConversionOptions(“filePDFA3b.log”, PdfFormat.PDF_A_3B, ConvertErrorAction.Delete);

We have investigated the earlier logged ticket and it has been closed now. The issue is connected to errors during incorrect validation on https://www.pdf-online.com/osa/validate.aspx.

Adobe Acrobat and AvePDF validators also show that the output document is valid.

Also, we can use Aspose.PDF to validate results:

Document pdfDocument = new Document(dataDir+"OUTPUTDOCUMENT.pdf");
System.out.println("is valid: "+ pdfDocument.validate(dataDir+"filePDFA3b_validate.log",PdfFormat.PDF_A_3B ));
