Thank you [~tallison]! (I was driving to home...)

I'm attaching my triggering file, it can be used for future tests, since it's from govdocs.

> 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.
