Tilman Hausherr commented on PDFBOX-5880:
-----------------------------------------
proposed change is to add {{stream.setLong(COSName.LENGTH, streamLength);}} or
change the foreach loop that it doesn't overwrite the length entry.
> PDF render blank page: The end of the stream doesn't point to the correct
> offset, using workaround to read the stream, stream start position: 196,
> length: 0, expected end position: 196
