Description Nicolas Bros CLA 2010-10-01 10:18:56 EDT 
- install eclipse-SDK-3.6-win32
- install MoDisco SDK from http://download.eclipse.org/modeling/mdt/modisco/updates/milestones/0.9
- open the "EPackage Registry" view

I get the following 4 exceptions:

Comment 1 Nicolas Bros CLA 2010-10-04 08:21:55 EDT 
I have noticed that generators created with Acceleo (classes extending AbstractAcceleoGenerator) manipulate the package registry (AbstractAcceleoGenerator#registerPackages).

Maybe this is linked?
