question about java client

After a bit of messing around, I'm now dropping objects into the correct bucket using the links annotation. However, I am noticing that the json is including the metadata from the domain object, i.e. things tagged with @RiakKey, @RiakIndex or @RiakLinks. I was under the impression this data would be left out. I wouldn't care a whole lot, but when I'm getting data back in via a fetch, the JSONConverter is crashing saying it doesn't know how to convert the RiakLink object since there isn't an appropriate constructor for it.
Do I need to specifically @JsonIgnore fields tagged with one of the Riak tags?
