Can you reopen the file you saved with PDFBox? If not, please open an
issue in JIRA and attach your file.
If yes, just upload the file somewhere, I'd like to have a look at the
encryption dictionaries.

Hi,
This is not a general problem and only occurs with original PDF generated with 3D content
using Anark. The file when loaded seems to have encrypted and loads just find in Adobe
Reader, but when we try to do a "Save As" we get the following error:
"The document could not be saved. There was a problem reading this document 21."
If I do a control click on the "ok" button. I get the following message:
"This direct object already has a container."
Any ideas what might be causing this problem? We have tried the same thing with
iText and it does not experience this problem.
Sample Code that reproduces the problem:
PDDocument doc = null;
try {
doc = PDDocument.load(pdfIn);
PDPage page = null;
AccessPermission apermission =
new AccessPermission();
apermission.setCanAssembleDocument(false);
apermission.setCanExtractContent(false);
apermission.setCanExtractForAccessibility(true);
apermission.setCanFillInForm(true);
apermission.setCanModifyAnnotations(true);
apermission.setCanPrint(true);
apermission.setReadOnly();
StandardProtectionPolicy spp = new
StandardProtectionPolicy(UUID.randomUUID().toString(), "", apermission);
doc.protect(spp);
for (int i = 0; i <
doc.getNumberOfPages(); i++) {
page =
doc.getPage(i);
PDPageContentStream canvas = new PDPageContentStream(doc, page,
PDPageContentStream.AppendMode.APPEND, true, true);
canvas.saveGraphicsState();
canvas.restoreGraphicsState();
canvas.close();
}
doc.save(pdfOut);
bRet = true;
}
finally {
if (doc != null) {
doc.close();
}
}
Thanks,
Patrick
