Description

The code generator does not support nested classes, e.g. consider the following pattern header:

pattern x(y : java org.eclipse.emf.ecore.util.FeatureMap.Entry) { ... }

The generator emits the following type declaration:

new JavaTransitiveInstancesKey(org.eclipse.emf.ecore.util.FeatureMap$Entry.class)

This results in a compile error.

Gábor Bergmann suspects that the problem is in the JavaTransitiveInstances constructor calls class.getName() instead of class.getCanonicalName() - it is worth checking.
