Perhaps the packages are not registered? 
Typical UI-like plugins have some magic in their activators that registers the EMF packages to EMF.

Betreff: Re: [mdt-bpmn2.dev] PackageNotFoundException when trying to load XML (or XMI) from a InputStream

Hi Jean,

I'm not sure what the problem is with your plugin, but I was able to get these files (and others) to load using the modelreader example plugin from the BPMN2 Modeler project [1].
The only difference I can see is that the modelreader code adds this before the load() call:

		HashMap<Object, Object> options = new HashMap<Object, Object>();
		options.put(XMLResource.OPTION_DEFER_IDREF_RESOLUTION, true);
		resource.load(options);

this causes forward references to objects by their IDs to be deferred until the entire file is loaded, but this shouldn't be the reason why this code works and yours doesn't.

HTH,
Bob
