Creating a builder from a DOMSource only works with Woodstox
------------------------------------------------------------

                 Key: AXIOM-401
                 URL: https://issues.apache.org/jira/browse/AXIOM-401
             Project: Axiom
          Issue Type: Bug
          Components: DOOM, LLOM
    Affects Versions: 1.2.12
            Reporter: Andreas Veithen
            Priority: Minor


Since Axiom 1.2.12, OMXMLBuilderFactory supports creating a builder from a 
javax.xml.transform.Source object. This works well for DOMSource objects, 
provided that Woodstox is used as StAX implementation. This can be demonstrated 
by the following code:

Document document = 
DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
document.appendChild(document.createElementNS(null, "root"));
OMDocument omDocument = OMXMLBuilderFactory.createOMBuilder(new 
DOMSource(document)).getDocument();
omDocument.serialize(System.out);

However, executing the same code using the StAX implementation included in 
Oracle's Java 1.6 runtime environment fails with the following error:

Exception in thread "main" java.lang.UnsupportedOperationException: Cannot 
create XMLStreamReader or XMLEventReader from a 
javax.xml.transform.dom.DOMSource
