             Summary: ZipDetector on a file should back off to streaming detection on failure to open a zipfile
                 Key: TIKA-3701
                 URL: https://issues.apache.org/jira/browse/TIKA-3701
             Project: Tika
          Issue Type: Task
            Reporter: Tim Allison


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.
