This reproduces the behaviour:

import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.output.Format;
import org.jdom2.output.XMLOutputter;

public class JDOMOutput {

    public static void main(String argv[]) throws Exception{
        Document document = new Document();
        Element root = new Element("root");
        document.addContent(root);
        Element sub1 = new Element("sub1");
        root.addContent(sub1);
        sub1.addContent(new Element("sub2").setText("Some text"));
        sub1.addContent(new Element("sub2").setText("  text with left
and right whitespace  "));
        new XMLOutputter(Format.getPrettyFormat().setTextMode(Format.TextMode.PRESERVE)).output(document,
System.out);
    }

}

Try with and without the setTextMode(Format.TextMode.PRESERVE). None
of them does what I need.
