             Summary: ClassCastException while extracting the text of a PDF
                 Key: TIKA-4443
                 URL: https://issues.apache.org/jira/browse/TIKA-4443
             Project: Tika
          Issue Type: Bug
          Components: parser
    Affects Versions: 3.2.0, 3.1.0, 3.0.0
            Reporter: Olivier Ceulemans
         Attachments: 112145_EXE_PI--_FEGI_MAT01_FT-0033_-0.pdf

A ClassCastException occurs when trying to extract the text of the attached PDF 
file with tika 3.2.0, 3.1.0, 3.0.0. I did not try previous versions.

A simple way to reproduce the issue is to use the 
org.apache.tika.example.SimpleTextExtractor class of the tika-example library, 
part of the distribution.

I also tried to use plain pdfbox without tika and the text can be extracted. 
That makes me assume that this could be a real issue rather than a corrupted 
PDF.

Here is the stack trace:
