+/**
+ * During a <code>cloneTree</code> call an updated reference was requested
+ * for a node that did not get cloned.  This happens when a sub-graph is
+ * duplicated via <code>cloneTree</code> and has at least one Leaf node
+ * that contains a reference to a Node that has no corresponding node in
+ * the cloned sub-graph. This results in two Leaf nodes wanting to share
+ * access to the same Node.
+ * <P>
+ * If dangling references are to be allowed during the cloneTree call,
+ * <code>cloneTree</code> should be called with the
+ * <code>allowDanglingReferences</code> parameter set to <code>true</code>.
