Made it the way you described with the exception that `DictWriter` actually encapsulates '`DictEntry`' (no need to perform `DictWriter dw = aw.dict()` rather use `DictWriter` itself to write the pairs; `aw` in this case is also `DictWriter`). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
