@Test
public void testByteArrayLess() {
  putTestEntitiesScalars();
  byte[] value = {1, 2, (byte) 2005};
  Query<TestEntity> query = box.query().less(simpleByteArray, value).build();
  List<TestEntity> results = query.find();
  assertEquals(5, results.size());
  // Java does not have compareTo for arrays, so just make sure its not equal to the value
  for (TestEntity result : results) {
    assertFalse(Arrays.equals(value, result.getSimpleByteArray()));
