Works for me with latest Jsoup (1.5.2).
String html = "<div class=\"content-text right-align bold-font\">foo</div>";
Document document = Jsoup.parse(html);
Elements elements = document.select("div.content-text.right-align.bold-font");
System.out.println(elements.text()); // foo
So either you’re possibly using an outdated version of Jsoup which exposes a bug related to this, or the actual HTML doesn’t contain a <div> like that.
