John Hewson commented on PDFBOX-3515:
-------------------------------------
OTFs contain a CFF font. CFF fonts come in two flavors, CID-keyed, and Type
1-Equivalent. The PDF contains a missing embedded font of type CIDFontType0,
which means it's expecting a CID-keyed CFF font. However, the substitute font
on your system is a Type 1-Equivalent CFF font, but PDFBox isn't expecting that
and so there is an exception.
This is a bug in PDFBox, which should be able to handle this eventuality. As a
workaround you could try and find another version of the CourierStd font which
is either a CID-keyed OTF, or a TTF, as those should work.
