Source code of the modified class.

I have an Ecore class A declaring an attribute whose type is declared as a class generic parameter. Class B extends class A and refines the type of the attribute to a specific data type. E.g.:

public class A<U extends Object>
   protected U unit;

public class B extends A<EEnumX>

where EEnumx is a specific Ecore enumeration declared in the meta-model.

Problem: A not serializable exception in thrown when producing an instance of class A because the proper type of the attribute (EEnumX) is not retrieved properly.

Fix: To fix this, I have redefined EMFModelAdapter.getType() so that if the attribute declares a generic type, the proper type is returned. I attach the modified EMFModelAdapter class.

A similar problem occurs with the Regular VM.
