Hopefully all you need to do is add the appropriate setting into the Java call in the xep.bat file here:
%programfiles%Common FilesXMetaL Sharedrenderxxep.bat
There is a thread on this particular issue answered by RenderX support here: http://services.renderx.com/lists/xep-support/3324.html
It is not specific to running XEP with the DITA OT but I suspect it must be the same problem.
