I didn't test your code but it is probably more difficult than that.
1) instead of asking, try the code and then check the result file with
the PDFBox Preflight command line application.
http://apache.mirror.iphh.net/pdfbox/1.8.7/preflight-app-1.8.7.jar
2) re "more difficult" - have a look at the source code of
PDFMergerUtility :-(

Dear All,
I would like to retain PDF/A compliance of the source document after
merging to a generated cover page. Also, I would like to retain the
bookmarks and metadata if it is existing from the source pdf. I have posted
this in Stackoverflow but no one answered. Here's the link to my SO post: How
to concatenate two pdfs and retain bookmarks and pdf/a compliance using
pdfbox?
<http://stackoverflow.com/questions/26695190/how-to-concatenate-two-pdfs-and-retain-bookmarks-and-pdf-a-compliance-using-pdfb>.
If somebody from the list can at least guide me on how to achieve this, I
would be very grateful.
Thanks in advance and regards,
