> SolrJ's DocumentObjectBinder maps custom objects to solr docs, either way.  It reads info about classes via reflection and stores it into a field.  I see no reason why this shouldn't be a global singleton since it's basically class metadata; its contents should be stable.  Today there's an instance of it on SolrClient and it has quirky use in QueryResponse.  I could see how this makes it possible to customize it by a user but there are other ways to do this.
