Marco Quaranta commented on TIKA-950:
-------------------------------------
Sadly I cannot write a unit test using the problematic file: it's italian
public administration-owned and it's confidential.
The error, if it could be interesting, is cause by ZipFile class.
This is the stacktrace:
java.util.zip.ZipException: error in opening zip file
at java.util.zip.ZipFile.open(Native Method)
at java.util.zip.ZipFile.<init>(ZipFile.java:127)

This error, as I said, doesn't happen using ZipInputStream.
I hope, however, I will find a similar file for testingaa

> Method detectOfficeOpenXML() in ZipContainerDetector class does not detect
> correctly an ooxml file due to an Exception throwed by OPCPackage.open(..)
> POI's class. This class make use of ZipFile when its method is called with
> (as Tika do) filePath string and in this way it generates an exception;
> passing instead a fileInputStream makes POI correctly detects OfficeOpenXML
> formats.
