Something new about getting comments from method body

Continuing the discussion from About comment in method body:

I have a new problem that I cannot get the comment behind which there is no code, when I use the solution About comment in method body - #3 by Quentin

It is the problem code:

@Test(expected = ZeroException.class)
  public void test_xxx() {
    // given
    int number1 = 1;
    int number2 = 0;
    // when
    int result = Calcutor.divide(number1, number2);
    // then

I guess the reason is that the comment then has no matched statement Tree, so it is discarded when sonar reading it?
