I've observed a lot of unwanted serialization artifacts from this module, most of which can be fixed by including this processor.  Now that the logic for fixing those artifacts is part of the module, the situation has improved - the long term concern is that it is too easy to overuse/misuse jackson, compounded when working with objects from third-party projects that were built for projects other than Apache Streams.  I don't have a good answer to propose at the moment - just wanted a note to designate that the class shouldn't be needed and should be deleted once the root cause is isolated and corrected.
