Nick Burch commented on TIKA-948:
---------------------------------
I've had a go at fixing this in r1358404, using a slightly different method.
Michael's suggested fix didn't seem to scale well to additional formats, and
would've been a bit confusing for the extractors.
Instead, I've updated POIFSContainerDetector to report that a CompObj that
isn't a known "native CompObj" has been found (older Works file, some older
Star files etc are all natively stored). This is reported in a similar way to
the OLE10Native stuff, which was slightly tweaked. I've then updated the
AbstarctPOIFSExtractor to then pull the data out of the CompObj structure.
Tika-App -z is then able to correctly extract the pdf out.
One remaining issue is with file extensions, a little bit more work is needed
to do that cleanly I think
