Hi,
I'd say this is either a bug in jempbox or in tika because of a bad
file. I agree tika shouldn't fail the entire request. At the very least
it's a documentation bug in jempbox. The current javadoc does not
mention what would happen with an incorrect value.
IMHO we should catch it in tika (PDMetadataExtractor) because this would
be only 1 step, i.e. we wouldn't have to wait for it to be fixed in jempbox.

PS: if you want you can resubmit your JIRA application, I'd approve it.
Just use the same name so I know it's you.

Hi,
I ran into a problem with Tika-server where pdf parsing fails
seemingly because pdf picture metadata xmp:Rating value is string not
expected integer[0-5].
Error with using: Tika-server 3.1.0.0-full docker image with Tesseract
OCR configured to extractInlineImages=true
Seemingly the cause of the error is PDF containing picture with
metadata: xmp:Rating="2.0"
Error:

Had to disable Tesseract ExtractInlineImages conf to process these
kinds of PDFs.
Is this a bug in tika logic or is there some sort of setting or
workaround that I'm missing? maybe tika could just ignore incorrect
xmp:Rating values with a warning, not fail the whole PDF processing?
Many thanks,
Siim
