I'm working with the Domainmodel Example, latest nightly build and hitting a NPE in the mentioned method, line 202:

if (isPackageKnown(superType.getEPackage().getNsURI())) {

In this case 'superType' is a proxy:
org.eclipse.emf.ecore.impl.EClassImpl@5f67bcdd (eProxyURI: archive:file:/Users/thoms/Development/Eclipse/eclipse-SDK-3.7M6/plugins/org.eclipse.emf.mwe2.language_2.0.0.v201103251505.jar!/../org.eclipse.xtext.common.types/model/JavaVMTypes.ecore#//JvmIdentifiableElement)
