Tim Allison commented on TIKA-3526:
-----------------------------------
I think you've solved a number of problems, but not all. This will take some
time. The xlsx file inside the docx file is in oleObject7.bin, which has an
Ole entry but no CompObj entry (which is what your code above and the original
code is checking for).
The other issue is that the streaming OPCPackageDetector is short-cutting to
tika-ooxml instead of waiting to read the {{[Content_Types].xml}}. This is
stored as the first physical object by MSWord, etc, but appears last in the
stream for WPS created files. :( We'll have to modify this, too.
