Description

We are using the latest version of PDFBox library 2.0.19. During the conversion of test file 1904.12320.pdf (which is a valid pdf file according to https://www.pdf-online.com/osa/validate.aspx) we get an error

java.lang.ClassCastException: org.apache.pdfbox.cos.COSString cannot be cast to org.apache.pdfbox.cos.COSDictionary

 

I am attaching also the stack trace:
