Insert a line break inside a paragraph in XWPFDocument

I am writing values into a word template using apache poi 3.8. I replace specific strings in a word file (keys) with required values, e.g. word document has a paragraph containing key %Entry1%, and I want to replace it with "Entry text line1 \nnew line". All replaced keys and values are stored in a Map in my realisation.

Map<String, String> replacedElementsMap;

The code for HWPFDocument is:

Range range = document.getRange();
for(Map.Entry<String, String> entry : replacedElementsMap.entrySet()) {
            range.replaceText(entry.getKey(), entry.getValue());
}

This code works fine, I just have to put \n in the entry string for a line break. However I can't find similiar method for XWPFDocument. My current code for XWPFDocument is:

List<XWPFParagraph> xwpfParagraphs = document.getParagraphs();
for(XWPFParagraph xwpfParagraph : xwpfParagraphs) {
            List<XWPFRun> xwpfRuns = xwpfParagraph.getRuns();
            for(XWPFRun xwpfRun : xwpfRuns) {
                String xwpfRunText = xwpfRun.getText(xwpfRun.getTextPosition());
                for(Map.Entry<String, String> entry : replacedElementsMap.entrySet()) {
                    if (xwpfRunText != null && xwpfRunText.contains(entry.getKey())) {
                        xwpfRunText = xwpfRunText.replaceAll(entry.getKey(), entry.getValue());
                    }
                }
                xwpfRun.setText(xwpfRunText, 0);
            }
        }

Now the "\n"-string doesn't result in the carriage return, and if I use xwpfRun.addCarriageReturn(); I just get a line break after the paragraph. How should I create new lines in xwpf correctly?

I have another solution and it is easier:

            if (data.contains("\n")) {
                String[] lines = data.split("\n");
                run.setText(lines[0], 0); // set first line into XWPFRun
                for(int i=1;i<lines.length;i++){
                    // add break and insert new text
                    run.addBreak();
                    run.setText(lines[i]);
                }
            } else {
                run.setText(data, 0);
            }
