Sean Bridges commented on PDFBOX-455:
-------------------------------------
I think the root cause is that the BaseFont value is a String (Courier
New,Bold) , while it should be a Name. The pdf is invalid. The dictionary is
correctly parsed.
An alternate solution might to check for this error after parsing a font, and
replace the COSString with a COSName. Having COSDictionary be lenient with
respect to the types it expects may make the parser more robust in other areas.
