Here's a patch (branch_4x) to reproduce the problem.
I'm working on the fix.
> SolrJ: CloudSolrServer atomic updates doesn´t work with Lists/Arrays
> (Objects, in general).

> Key: SOLR-4080

> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.0
> Environment: Solr 4.0 with SolrCloud deployed with two SolrServers
> with shards=1. solr-solrj artifact version 4.0.0 is used to execute atomic
> update operations.

> Atomic updates with a CloudSolrServer object instance doesn´t work properly.
> - Code snippet:
> // CloudSolrSever instance.
> LBHttpSolrServer lbSolrServer = new LBHttpSolrServer(solrEndpoints);
> CloudSolrServer cloudSolrServer = new CloudSolrServer(zookeeperEndpoints,
> lbSolrServer);
> // SolrInputDocument to update:
> SolrInputDocument do = ne SolrInputDocument();
> doc.addField("id", "myId");
> Map<String, List<String>> operation = new HashMap<String, List<String>>();
> operation.put("set", [[a list of String elements]]); // I want a set
> operation to override field values.
> doc.addField("fieldName", operation);
> // Atomic update operation.
> cloudSolrServer.add(doc);
> - Result:
> doc: {
> id: "myId",
> fieldName: [ "{set=values}"
> ],
> ...
> }
> - Changing map from snippet like Map operation = new HashMap() instead of
> Map<String, List<String>> operation = new HashMap<String, List<String>>()
> obtains the following result after the atomic update:
> doc: {
> id: "myId",
> fieldName: ["[Value1, Value2]"
> ],
> ...
> }
> - Also, the old value is never erased, and instead of a "set" operation an
> "add" operation happens.
> CONCLUSION: during an atomic update with CloudSolrServer the
> List/Array/Object value passed is being processed with just a toString()
> method.
