I don't know of any other test tools, at least not for coverage.
If you want to know the line number of a specific place, then you could use this trick:
Coverage.dumpLineNumber();
// Coverage is just your own class with the static method getLineNumber()
// dumpLineNumber():
public void dumpLineNumber() {
  try {
    throw new Exception();
  } catch (Exception e) {
    StringWriter sw = new StringWriter();
    PrintWriter pw = new PrintWriter(sw, true);
    e.printStackTrace(pw);
    String stackTrace = sw.toString();
    // line 3 or so is the line containing the linenumber
    System.out.println(stackTrace);
    StringTokenizer st = new StringTokenizer(stackTrace, "\n\r");
    st.nextToken();
    st.nextToken();
    String s = st.nextToken();
    int i = s.indexOf(":");
    if (i != -1) {
      String line = s.substring(s.indexOf(":")+1, s.length()-1);
      System.out.println("Line: "+line);
}This of course works only if the stack trace dumped by the jvm shows the line numbers.
