Andriy updated PDFBOX-1510:
---------------------------
Description:
When a PDF is attached to another PDF it gets corrupted when retrieved through
PDEmbeddedFile.getByteArray() method call. For some reason the returned array
has less data than the original file that has been attached to the PDF.
This affects some of the documents and not another (see attachments for
working/non-working files), source code reproducing the issue has been attached
as well.
was:
When a PDF is attached to another PDF it gets corrupted when retrieved through
PDEmbeddedFile.getByteArray() method call. For some reason the returned array
has less data than the original file that has been attached to the PDF.
This affects some of the documents and not another. Below is the test code the
replicates the issue.
PDF that has an attachment that gets corrupted will be attached to the issue.
