@Test
  public void test() throws IOException {
    String os = System.getProperty("os.name").toLowerCase();
    if (os.startsWith("windows")) {
      testStartClientOnWindows(".bat", os);
    } else {
      testStartClientOnUnix(".sh", os);
    }
  }
This test case is strange that it relies on the maven output files
