Description

The IdentifyMimeType processor doesn't identify CSV files as text/csv.

As far as I can tell the reason is that the Tika Detector identifies some mime types just based on the input filename rather than the content. IdentifyMimeType doesn't appear to be passing in the filename to the metadata provided to the Detector when doing detection [1].
