library: org.eclipse.emf.ecore.change_2.5.0.v20100521-1846.jar
package: org.eclipse.emf.ecore.change.util
class: BasicChangeRecorder
method:   protected FeatureChange getFeatureChange(List<FeatureChange> featureChanges, EStructuralFeature eStructuralFeature)
line: 243
--------------------
EObjectContainmentEList<FeatureChange> changes = (EObjectContainmentEList<FeatureChange>)featureChanges;
--------------------

It casts the "List<FeatureChagne"> to "EObjectContainmentEList<FeatureChange>", but there is no code which need to use the EObjectContainmentEList.
It is not necessary to do this casting.

Reproducible: Always

Steps to Reproduce:
1. Create some ecore model that has a containment reference.
2. Generate the code
3. By default, it will create the containment reference list using EObjectContainmentEList. 
4. Try to create this list with other List type, which is not inherit from EObjectContainmentEList.
5. Try to change value of this list. The BasicChangeRecorder.getFeatureChange(..) will be called.
