Hi,

I'm trying to use EMF Compare programmaticly:

MatchModel match = MatchService.doMatch(referenceModel,
createdModel, Collections.<String, Object> emptyMap());
// Computing differences
DiffModel diff = DiffService.doDiff(match, false);

Both models are UML-models and they do exist (are not null).

Unfortunatly, the first line already throws a NullPointerException:

java.lang.NullPointerException
