Fixed.

It was another issue with org.apache.poi.ddf.EscherArrayProperty.
(We already had issues with it, see  Bug 39800). 
In PPT it is legal to have empty complex part of an array property. When reading
such a property, remember it and write back the same empty data. 
Although the fix is simple I spent a lot of time trying to cover all sorts of
special cases in xls and ppt.
Truly, the Escher arrays are the most weird constructions ever intended :).

P.S. I moved the warning messages to POILogger. If users want verbose output
they should enable it through -Dorg.apache.poi.util.POILogger option.
For example to use System.out set it as follows:
-Dorg.apache.poi.util.POILogger=org.apache.poi.util.SystemOutLogger

Regards,
Yegor
