The project containing the ExampleLauncher class and models

I try to run the ExampleLauncher class(the standalone example from the provided examples by EMF Compare) in Eclipse in order to compare two uml models programatically. The application crashes with the following exception:

Additional information: The same uml models are compared with the emf compare editor and I can obtain the res1.emfdiff file (in the attachment)
Comment 1 Laurent Goubet CLA 2011-08-09 06:01:49 EDT 
We had issues with proxy resolution and copying objects that were in "unmodifiable" resources; winding up with errors such as this one. This has now been fixed on both master and the 1.2 maintenance stream.

The builds fixing this issue are :
 - 1.2 integration : I201108090404
 - 1.3 integration : I201108090415
