OK, now we have a problem. I tried
https://www.pdf-online.com/osa/validate.aspx
Validating file "PDFA.pdf" for conformance level pdfa-1b
dc:title/*[0] :: Missing language qualifier.
The document does not conform to the requested standard.
The document's meta data is either missing or inconsistent or corrupt.
The document does not conform to the PDF/A-1b standard.
Done.
and veraPDF:

I was using your CreatePDFA java code to create a PDF/A document but the
validator web site was saying it was not a true PDF/A
