Issue in casting a anyxml leaf to anyXMLNode type

I am getting WARNING when trying to get values of datastore-contents-xml anyxml node for below notification.

Is there any modification to anyXML implementation? How to convert anyxml data to a DOMSource in current implementation?

NOTE: It was working fine during Dec time line.

The value I am getting for below notification looks

Notification schema:

leaf time-of-update

Sample code:

catch (Exception e)

{ LOG.warn(e.toString()); }

String notificationAsString = domSourceToString(domSource);
LOG.info("Notification recieved for sub_id :{} at : {}:\n {}", sub_id, timeofeventupdate, notificationAsString);
