> When using PDFMergerUtility to merge the attached PDF twice into one document there may be data missing.
> To be more specific: In this case the data on page 1 looks fine, but page 28 is empty. My expectation is that page 28 is identical to page 1 (the document has 27 pages).
> Of course that's not a common use case. But I can reproduce this behaviour with other documents which are not identical, but similar.
> I think this might be related to PDFBOX-3111 and PDFBOX-3218.
> What is the trigger for this and is there a workaround?
