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.
