This seems to work, though it gives subsequences as well:

(To be fair, this was built off of Guillame's code)

public static void main(final String[] args) {
    // final String s = "RonRonJoeJoe";
    // final String s = "RonBobRonJoe";
    final String s = "aaabbaaacccbb";

    final Pattern p = Pattern.compile("(.+).*\\1");

    final Matcher m = p.matcher(s);
    int start = 0;
    while (m.find(start)) {
        System.out.println(m.group(1));
        start = m.toMatchResult().end(1);
    }
}
