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.
