I didn't. I'm not recreating JSON from the SolrJ results. I would try to use the same classes that SolrJ uses, actually. (Writing that without having a further look at the code.) I would avoid recreating existing code as much as possible. About multivalued fields: you need instanceof checks, I guess. The field only contains a list if there really are multiple values. (That's what works for my ScriptTransformer.) Are you sure that you cannot change the SOLR results at query time according to your needs? Maybe you should ask for that, first (ask for X instead of Y...).
