@Test
public void testEmptySort() throws IOException, IllegalAccessException {
  SimpleFeatureSource fsp = getFeatureSource(SystemTestData.PRIMITIVEGEOFEATURE);
  Query q = new Query();
  q.setSortBy(SortBy.UNSORTED);
  SimpleFeatureCollection fc = fsp.getFeatures(q);
  // the above call used to add a SortedSimpleFeatureCollection wrapper that in turn killed
  // some visit optimizations
  while (fc instanceof DecoratingFeatureCollection) {
    assertThat(fc, not(instanceOf(SortedSimpleFeatureCollection.class)));
    Field field =
        FieldUtils.getDeclaredField(SortedSimpleFeatureCollection.class, "delegate");
    field.setAccessible(true);
    Object delegate = field.get(fc);
    fc = (SimpleFeatureCollection) delegate;
  }
