Calling close does not seem to close a connection

  @Test
  public void testStreamOnClosedConnection() {
    String sql = "SELECT ID, FNAME, LNAME FROM select_table ORDER BY ID";
    final AtomicInteger cnt = new AtomicInteger(0);
    final SQLConnection conn = connection();

    conn.queryStream(sql, onSuccess(res -> {
      conn.close();

      res.resultSetClosedHandler(v -> {
        fail("Should not happen");
      }).handler(row -> {
        fail("Should not happen");
      }).endHandler(v -> {
        fail("Should not happen");
      }).exceptionHandler(t -> {
        testComplete();
      });
    }));

    await();
  }
