Wolfgang Wachsmuth commented on PDFBOX-4915:
--------------------------------------------
Hi,
sorry for asking in this closed issue. I am not sure if it is correct. I have a
similar PDF perfectly fine to open in acrobat reader but failing to open with
PdfBox. I am pretty sure there must be an issue with the PDF but despite
reading all comments/commits and debugging I am not sure what's wrong. Sadly
the PDF has some sensible data, so I can not just upload it.
Can somebody tell me if the xref table is looking fine or to what signs I have
to look (same exception as OP):

The generator of the PDF seems to be
{{/Producer (StreamServe Communication Server 16.6.2 GA Build 397 \(64 bit\))}}
But I also have PDFs from the same "producer" with working PDF.
Thank you!
