Description Kenn Hussey CLA 2011-06-10 11:07:10 EDT 
A concurrent modification exception occurs while consolidating the changes in a change recorder that is attached to objects with (unresolved) container proxies:

Caused by: java.util.ConcurrentModificationException
   at org.eclipse.emf.common.util.AbstractEList$EIterator.checkModCount(AbstractEList.java:762)
   at org.eclipse.emf.common.util.AbstractEList$EIterator.doNext(AbstractEList.java:710)
   at org.eclipse.emf.common.util.AbstractEList$EIterator.next(AbstractEList.java:696)
   at org.eclipse.emf.ecore.change.util.ChangeRecorder.consolidateChanges(ChangeRecorder.java:231)


The fix is to change the isOrphan(EObject) method like this:

protected boolean isOrphan(EObject eObject) {
	return ((InternalEObject) eObject).eInternalContainer() == null && eObject.eResource() == null;
}
