Pretty print XML in Java like Eclipse does

Given the following XML structure:

    Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
    Element root = document.createElement("root");
    Element child = document.createElement("child");
    root.appendChild(child);

And the following transformer with the specified output properties:

    Transformer transformer = TransformerFactory.newInstance().newTransformer();
    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
    transformer.setOutputProperty(OutputKeys.INDENT, "yes");
    transformer.setOutputProperty("{http://ift.tt/1fh1NGB", "4");
    transformer.transform(new DOMSource(root), new StreamResult(System.out));

I get this expected result:

<?xml version="1.0" encoding="UTF-8"?><root>
    <child/>
</root>

Which output properties do I need to produce the following output?

<?xml version="1.0" encoding="UTF-8"?>
<root>
    <child />
</root>

I need something to get a line break after the xml header and a whitespace before the close of empty tags. (like formatting in Eclipse)

My transformer is the default com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl.
