Answering my own question. This can be achieved by setting the following on
the JacksonJsonProvider instance:
JacksonJsonProvider jjp = new JacksonJsonProvider();
jjp.configure(Feature.WRITE_NULL_MAP_VALUES, false);
jjp.configure(Feature.WRITE_NULL_PROPERTIES, false);
A full description of my solution can be found in response to my stack
overflow question (

Thanks to Tatu Saloranta for all the help provided.
