Using JDom b9, and given the following xml...

<?xml version="1.0" encoding="UTF-8"?>
<root>
<tag1>ABC</tag1>
<tag2>123</tag2>
</root>

...assume I have the above XML in a valid Document object "doc"
and I do this in my code...

Element root = doc.getRootElement();
root.addContent(new Element("tag2").addContent("456"));

What happens?

Do I end up with duplicate "tag2" tags?

Does "tag2" get replaced?

Is an exception thrown?

...
