When notification is disabled when generating the model, calling isSetXXX() on a list will trigger a ClassCastException.

        A a = AFactory.eINSTANCE.createA();
        B b = AFactory.eINSTANCE.createB();
        a.getBs().add(b);
        a.isSetBs(); // classcastexception here

java.lang.ClassCastException: org.eclipse.emf.ecore.util.BasicInternalEList cannot be cast to org.eclipse.emf.ecore.util.InternalEList$Unsettable
	at a.impl.AImpl.isSetBs(AImpl.java:94)
	at emfplayground.Unset.list(Unset.java:17)
	at 

The bug is in the generated code:
    public EList<B> getBs() {
        if (bs == null) {
            bs = new BasicInternalEList<B>(B.class);
        }
        return bs;
    }

Reproducible: Always
