[ERROR] ExitStatusException occurred while running workflow: Java returned: 1

investigation:
* the feature of XFeatureCall is just an eProxy (but should be for example the 
name feature of mod4j's StringProperty)

current diagnose:
* XbaseScopeProvider.THIS is not properly bound resp. mod4j not properly loaded 
/ resolved inside model inferer

Work around: do not use XExpressions, to get the examples above woking again 
you have to write:
* name into textId2
* name into uniqueRuleName
