Target class is here:

 private final TextBox serveripValueWidget = new TextBox();
 public EndPointWidget() {
        initForm();
  }

 private void initForm() {
        serveripValueWidget.setMaxLength(50);
}

Test case is here:

    @Test
    public void setData() {
        EndPointWidget epw = new EndPointWidget(); //error happen.
    }

Thanks for the clear report / repro case. Looks like the same sort of issue as #33. Should be fixed in the latest snapshot now if you'd like to try it out.
