> 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:
