Problem is related with line this line: NotationUtils.getNotationModel((ModelSet)containingResource.getResourceSet()).getResourceURI().trimFileExtension(); NotationUtils.getNotationModel() can return null getResourceURI() can return null This cases should be checked :)
I don't know whether the bug still occurs. I could not reproduce it. To be sure, I've added NPE checks in the LoadingTester. Done in r8650.
