Description

XmlConvertor cannot convert from org.apache.xerces.dom.ElementNSImpl to org.w3c.dom.Document. Class ElementNSImpl implements both interfaces org.w3c.dom.Node and org.w3c.dom.NodeList. While type converter lookup iterates from ElementNSImpl through it's superclasses and implemented interfaces, it reaches NodeList first. Therefore the

Node toDOMNodeFromSingleNodeList(NodeList)

method is selected for conversion. However this method returns null for any NodeList with more than one node. This leads to null in a message's body.
This issue is not detected on Linux, because on Oracle JDK lookup reaches Node before NodeList and the

Document toDOMDocument(Node)

method is selected for conversion.
