Jackson is not deserialising a generic list that it has serialised

When using Apache Jersey with Jackson for JSON serialisation (on both server and client), I'm hitting a problem when deserialising a generic List.

The JSON I am producing is as follows, all 3 classes in "data" implement "CheckStatusDetail":

{
  "errorCode" : 0,
  "errorMessage" : null,
  "type" : "array",
  "data" : [ {
    "@class" : "com.rrr.base.status.module.dto.DiscoveryAgentCheckStatusDetail",
    "serverInfo" : {
      "@class" : "com.rrr.base.util.discovery.config.xml.XMLServerInfo",
      "name" : "java",
      "location" : "THEO",
      "description" : "sddgs",
      "group" : "java",
      "aliases" : [ "mercury" ]
    }
  }, {
    "@class" : "com.rrr.base.status.module.dto.MongoDBCheckStatusDetail",
    "addresses" : [ "localhost:27017" ],
    "version" : "2.5",
    "connected" : true
  }, {
    "@class" : "com.rrr.base.status.module.dto.NetworkCheckStatusDetail",
    "splitBrain" : false
  } ],
  "count" : 3,
  "status" : 0
}

The object that produces this JSON looks like this, I'm using the same class on the client side:

public class NSResponse<T> implements Serializable {

    private static final long serialVersionUID = 1L;

    public static final int STATUS_OK       = 0;
    public static final int STATUS_ERROR    = -1;

    public static final String TYPE_OBJECT  = "object";
    public static final String TYPE_ARRAY   = "array";

    private int status;
    private int errorCode;
    private String errorMessage;
    private String type;

    private List<T> data;

    private int count;

    public NSResponse() {   }

    public NSResponse(int errorCode, String errorMessage) {
        this.status = STATUS_ERROR;
        this.errorCode = errorCode;
        this.errorMessage = errorMessage;
    }

    public NSResponse(T data) {
        this.status = STATUS_OK;
        this.type = TYPE_OBJECT;
        this.data = new ArrayList<T>();
        this.data.add(data);
