Tilman Hausherr commented on PDFBOX-4809:
-----------------------------------------
Which PDPageContentStream constructor is used? From looking at the source code,
I think that "output" is null... but this is impossible from construction IMHO.
Or could it be your code calls beginText() despite having called close() before
that?
