ReferencedImplicitElementException when using Collections.EMPTY_LIST

I am using implicit collections and trying to serialize objects that sometimes have the collection set to java.util.Collections.EMPTY_LIST. I think that XStream should be able to handle this situation, but I get a ReferencedImplicitElementException.

In AbstractReflectionConverter's doMarshal() method, I would add a check to see if the object is an empty collection or array, and if it is, do not register the implicit with a ReferencingMarhasllingContext.)
