Buggy source:
public void testSeparateIds(){
  RecordImpl createRecord=(RecordImpl)requestFactory.create(SimpleFooRecord.class);
  assertTrue(createRecord.isFuture());
  Long futureId=createRecord.getId();
  RecordImpl mockRecord=new RecordImpl(RecordJsoImpl.create(futureId,1,SimpleFooRecordImpl.SCHEMA),RequestFactoryJsonImpl.NOT_FUTURE);
  valueStore.setRecord(mockRecord.asJso(),requestFactory);
  DeltaValueStoreJsonImpl deltaValueStore=new DeltaValueStoreJsonImpl(valueStore,requestFactory);
  deltaValueStore.set(SimpleFooRecord.userName,createRecord,"String_Node_Str");
  deltaValueStore.set(SimpleFooRecord.userName,mockRecord,"String_Node_Str");
  assertTrue(deltaValueStore.isChanged());
  String jsonString=deltaValueStore.toJsonWithoutChecks();
  JSONObject jsonObject=(JSONObject)JSONParser.parse(jsonString);
  assertFalse(jsonObject.containsKey(WriteOperation.DELETE.name()));
  assertTrue(jsonObject.containsKey(WriteOperation.CREATE.name()));
  assertTrue(jsonObject.containsKey(WriteOperation.UPDATE.name()));
  JSONArray createOperationArray=jsonObject.get(WriteOperation.CREATE.name()).isArray();
  assertEquals(1,createOperationArray.size());
  assertEquals("String_Node_Str",createOperationArray.get(0).isObject().get(SimpleFooRecord.class.getName()).isObject().get(SimpleFooRecord.userName.getName()).isString().stringValue());
  JSONArray updateOperationArray=jsonObject.get(WriteOperation.UPDATE.name()).isArray();
  assertEquals(1,updateOperationArray.size());
  assertEquals("String_Node_Str",updateOperationArray.get(0).isObject().get(SimpleFooRecord.class.getName()).isObject().get(SimpleFooRecord.userName.getName()).isString().stringValue());
}

Fixed version (ground truth):
public void testSeparateIds(){
  RecordImpl createRecord=(RecordImpl)requestFactory.create(SimpleFooRecord.class);
  assertTrue(createRecord.isFuture());
  Long futureId=createRecord.getId();
  RecordImpl mockRecord=new RecordImpl(RecordJsoImpl.create(futureId,1,SimpleFooRecordImpl.SCHEMA),RequestFactoryJsonImpl.NOT_FUTURE);
  valueStore.setRecord(mockRecord.asJso(),requestFactory);
  DeltaValueStoreJsonImpl deltaValueStore=new DeltaValueStoreJsonImpl(valueStore,requestFactory);
  deltaValueStore.set(SimpleFooRecord.userName,createRecord,"String_Node_Str");
  deltaValueStore.set(SimpleFooRecord.userName,mockRecord,"String_Node_Str");
  assertTrue(deltaValueStore.isChanged());
  String jsonString=deltaValueStore.toJson();
  JSONObject jsonObject=(JSONObject)JSONParser.parse(jsonString);
  assertFalse(jsonObject.containsKey(WriteOperation.DELETE.name()));
  assertTrue(jsonObject.containsKey(WriteOperation.CREATE.name()));
  assertTrue(jsonObject.containsKey(WriteOperation.UPDATE.name()));
  JSONArray createOperationArray=jsonObject.get(WriteOperation.CREATE.name()).isArray();
  assertEquals(1,createOperationArray.size());
  assertEquals("String_Node_Str",createOperationArray.get(0).isObject().get(SimpleFooRecord.class.getName()).isObject().get(SimpleFooRecord.userName.getName()).isString().stringValue());
  JSONArray updateOperationArray=jsonObject.get(WriteOperation.UPDATE.name()).isArray();
  assertEquals(1,updateOperationArray.size());
  assertEquals("String_Node_Str",updateOperationArray.get(0).isObject().get(SimpleFooRecord.class.getName()).isObject().get(SimpleFooRecord.userName.getName()).isString().stringValue());
}
