Maxim Valyanskiy commented on TIKA-877:
---------------------------------------
I think it is not a real problem, because "file5" is invalid Ole10Native
attachement.
Tika 1.0 saves internal data stream of that entry prepended by some headers
that it could not parse. Current (trunk) version saves complete Ole10Native
stream when entry is not valid.
> Embedded document not extracted (regression)

> Notice how 1.0 could extract the data for file5, but 1.1 creates an empty

> By the way, I do see improvements in 1.1 as well, congrats for that!
