Description

On a PDF document, which opens fine with Adobe Reader and Preview on Mac OS, the PDDocument.load() method throws the following:

java.io.IOException: expected number, actual=COSFloat{18446744073430152624} at offset 33182

Sorry the material is sensitive so I can't attach it 

 

However if I cat the file it looks like this around the offset:
