Big PDF file throws confusing not catchable exception


we try to handle (Remove first Page) a big (2.7 GB) PDF file.
1.) If i try to load the File calling “Document pdfDocument = new Document(bigFile)”, surrounded with a try…catch construct an exception will be thrown which i cannot catch in my code, because it will be thrown only internally!!! The code simple stop working.
2.) The exception said (german): “Es wurde versucht, den Dateizeiger vor den Anfang der Datei zu bewegen.”

Here is the file (hope the OneDrive sharing works fine) :!AjOcEJEeBU1Oa3OA0dAvYCr1txs?e=X0oJSS

Kind Regards,


We tried to download the file that you have uploaded to One Drive but we could not obtain it. The downloading process never started. Would you please confirm if the file is uploaded correctly and is able to download by us?


i shared it to two more people and they got no problems…?
I tried it from an other location and the download starts (see screenshot).
