Big PDF file throws confusing not catchable exception

Hello,

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) :

Kind Regards,
Andy
