Resetting Default Namespace Using JDOM

Question

Is it possible to reset the default namespace on a JDOM Document? I've tried setting a namespace declaration on the root element with the following code:
Element myRootElement = myDocument.getRootElement();
Namespace namespace = Namespace.getNamespace("http://whatever.com");
myRootElement.addNamespaceDeclaration(namespace);Since the Document already has a default namespace, I get the following stack trace:
org.jdom.IllegalAddException: The namespace xmlns="http://whatever.com" could not be added as a namespace to "rdf:RDF": The namespace prefix "" collides with an additional namespace declared by the element
     at org.jdom.Element.addNamespaceDeclaration(Element.java:339)Does anyone have any suggestions or hints? Perhaps its not even possible? Thanks in advance for any help.

pass the RootElement to the following method:
public void someMethod(org.jdom.Element element) {
org.jdom.Namespace xhtml = org.jdom.Namespace.getNamespace("html","http://www.watever.com");
if (element.getNamespace() == org.jdom.Namespace.NO_NAMESPACE) {
element.setNamespace(xhtml);
java.util.List childElements = element.getChildren();
java.util.Iterator iterator = childElements.iterator();
while (iterator.hasNext()) {
org.jdom.Element child = (org.jdom.Element) iterator.next();
someMethod(child);
}
