Ugh, formatting mess.
For more info, this is the "addOCGs:OCG" log line just before the error
message:

I'm using PDFBox 3.0.0 to combine some PDF files. One of the files
uses an Optional Content Group.
Note that this code has been working just fine for many other files
both with and without OCG's.
For this file, I get this exception:

Code:

PDOptionalContentGroup grp= *new*PDOptionalContentGroup(dict);
ocProps.addGroup(grp);
ocProps.setGroupEnabled(grp, layersON.contains(grp.getName()));
changed= *true*;
}
}
It's failing on the "new PDOptionalContentGroup(dict)" call.
Any ideas on why?
