Rightclicking both files shown below and comparing them with each other yields three changes:
- order change of eClassifiers
- del reference http://www.eclipse.org/emf/2002/Ecore#//EByteObject
- add reference http://www.eclipse.org/emf/2002/Ecore#//EByteObject
although the only modification is the order of eClassifiers.

Tested with Eclipse 3.6M7.

The files shown below are also attached to this bug.

Comment 2 Laurent Goubet CLA 2011-08-09 05:58:18 EDT 
The match, diff and merge process have seen a great deal of improvement in the
past week, with the addition of unit tests for most of the different use cases
(one use case = one possible "diff" between models) we could think of.

This particular issue can no longer be reproduced with these improvements.

These changes have been pushed on both master and the 1.2 maintenance stream.
They are available in the builds
 - 1.2 integration : I201108090404
 - 1.3 integration : I201108090415
