IdStory Identity Manager

Tested on version: 10.3.2
Tested on CzechIdM installed in a production-ready version (https://wiki.czechidm.com/tutorial/adm/czechidm_installation), or in Demo, or in IdM running locally in Eclipse.
When trying to run an import batch, we get following exception:

The file /opt/czechidm/data/temp/6710554196477292052/SysSystemDto really doesn't exist.

The same import batch runs correctly on Windows.
