You'll have to do element.setText("test\ntest"), leaving out the \r

Read section 2.11 End-of-Line handling and consider round-tripping (going
from a text file, to JDOM, back to a text file).  The problem is for JDOM to
ever have a Text node with \r in it, and to ensure that round-tripping works,
then the original text file would have to have used a char. reference like
&#xD. Otherwise the \r would have been normalized.
