Tilman Hausherr commented on PDFBOX-3660:
-----------------------------------------
I tested the behavior of Adobe Reader with different versions of the file from
PDFBOX-3679: when the array is missing, Adobe does like it is \[0 0 1] which is
described in the specification. But when it is there but too short, the missing
elements are treated as 0.
