You need to update the security.policy file to include the following line: (java.util.PropertyPermission "HSSFWorkbook.SheetInitialCapacity" "read")
You can find this file locally at the modeler install folder\modeler\runtemplates\deployment\data\
Hope this helps
You could also try disabling "Emulate cloud security". Under Project, Settings, edit the active Configuration. Go to Server and check "No" for "Emulate cloud security".
