Andrea Vacondio commented on PDFBOX-2845:
-----------------------------------------
I took a quick look and the issue is that object 515 is a stream, its length is
an indirect object (554) which is defined in an Object Stream. Currently PDFBox
requires the stream length to not being defined in an object stream as per PDF
spec chap. 7.5.7.
