Tilman Hausherr commented on PDFBOX-5275:
-----------------------------------------

It's something with the OCGs... it works if one comments the first line (orange 
lines appears).

The bug is in OCMD handling... {{Root/Pages/Kids/[4]/Resources/Properties/OC0}} 
has an empty OCGs array and this is mishandled, despite that the specification 
says "If this entry is not present, is an empty array, or contains references 
only to null or deleted objects, the membership dictionary shall have no effect 
on the visibility of any content."
