------------------------------------------
Thank you [~tallison]! (I was driving to home...)
I'm attaching my triggering file, it can be used for tests, since it's from
govdocs.
> ZipDetector on a file should back off to streaming detection on failure to
> open a zipfile

>
> If a file is passed to Tika wrapped as a TikaInputStream with an underlying
> file, the DefaultZipDetector tries to open a ZipFile. If there's a truncated
> file or if that ZipFile open fails, the DefaultZipDetector effectively gives
> up.
> Given that there's still a file available, we should try to do a streaming
> detect by reopening the file as a regular InputStream.
> If we don't do this, we wind up getting different detection for some
> truncated ooxml if the user sends in a file vs a stream.
