Buggy source:
public boolean startElement(XPathFragment xPathFragment,UnmarshalRecord unmarshalRecord,Attributes atts){
  try {
    XMLContext xmlContext=unmarshalRecord.getUnmarshaller().getXMLContext();
    workingDescriptor=findReferenceDescriptor(xPathFragment,unmarshalRecord,atts,xmlAnyObjectMapping,xmlAnyObjectMapping.getKeepAsElementPolicy());
    if (workingDescriptor == null) {
      QName qname=new QName(xPathFragment.getNamespaceURI(),xPathFragment.getLocalName());
      workingDescriptor=xmlContext.getDescriptor(qname);
      if (workingDescriptor != null && workingDescriptor.isWrapper()) {
        workingDescriptor=null;
      }
    }
    UnmarshalKeepAsElementPolicy policy=xmlAnyObjectMapping.getKeepAsElementPolicy();
    if (((workingDescriptor == null) && (policy == UnmarshalKeepAsElementPolicy.KEEP_UNKNOWN_AS_ELEMENT)) || (policy == UnmarshalKeepAsElementPolicy.KEEP_ALL_AS_ELEMENT)) {
      setupHandlerForKeepAsElementPolicy(unmarshalRecord,xPathFragment,atts);
    }
 else     if (workingDescriptor != null) {
      processChild(xPathFragment,unmarshalRecord,atts,workingDescriptor,xmlAnyObjectMapping);
    }
 else {
      AnyMappingContentHandler handler=new AnyMappingContentHandler(unmarshalRecord,xmlAnyObjectMapping.usesXMLRoot());
      String qnameString=xPathFragment.getLocalName();
      if (xPathFragment.getPrefix() != null) {
        qnameString=xPathFragment.getPrefix() + "String_Node_Str" + qnameString;
      }
      handler.startElement(xPathFragment.getNamespaceURI(),xPathFragment.getLocalName(),qnameString,atts);
      unmarshalRecord.getXMLReader().setContentHandler(handler);
      return true;
    }

Fixed version (ground truth):
public boolean startElement(XPathFragment xPathFragment,UnmarshalRecord unmarshalRecord,Attributes atts){
  try {
    XMLDescriptor workingDescriptor=findReferenceDescriptor(xPathFragment,unmarshalRecord,atts,xmlAnyObjectMapping,xmlAnyObjectMapping.getKeepAsElementPolicy());
    UnmarshalKeepAsElementPolicy policy=xmlAnyObjectMapping.getKeepAsElementPolicy();
    if (((workingDescriptor == null) && (policy == UnmarshalKeepAsElementPolicy.KEEP_UNKNOWN_AS_ELEMENT)) || (policy == UnmarshalKeepAsElementPolicy.KEEP_ALL_AS_ELEMENT)) {
      setupHandlerForKeepAsElementPolicy(unmarshalRecord,xPathFragment,atts);
    }
 else     if (workingDescriptor != null) {
      processChild(xPathFragment,unmarshalRecord,atts,workingDescriptor,xmlAnyObjectMapping);
    }
 else {
      AnyMappingContentHandler handler=new AnyMappingContentHandler(unmarshalRecord,xmlAnyObjectMapping.usesXMLRoot());
      String qnameString=xPathFragment.getLocalName();
      if (xPathFragment.getPrefix() != null) {
        qnameString=xPathFragment.getPrefix() + "String_Node_Str" + qnameString;
      }
      handler.startElement(xPathFragment.getNamespaceURI(),xPathFragment.getLocalName(),qnameString,atts);
      unmarshalRecord.getXMLReader().setContentHandler(handler);
      return true;
    }
  }
 catch (  SAXException e) {
    throw XMLMarshalException.unmarshalException(e);

  return true;
