Tim Allison commented on TIKA-2115:
-----------------------------------
Thank you for opening this. I think we'll have to fix this at the POI level,
because at the Tika level, I'm getting {{nativeEntry}}'s size as 4100 and
{{part}}'s size as 7168. Something appears to be going wrong in the
calculation of {{dataSize}} in Ole10Native's initialization.

> There is a size field when parsing an embedded OLE object in a Powerpoint
> presentation that says there are 2GB of data that needs to be read and the
> code simply tries to allocate a buffer for that, which results in OOM.
