elasticsearch Get aggregations in Java

How can I get the aggregations of a query in Java?

This is my query:

GET my_dataset/document/_search
     {
        "query": {
             "match": {
                 "docId": "1"
            }
        },
        "aggs": {
            "text": {
                "avg": {
                    "script": "doc['text'].values.size()" 
               }
            }
        }
     }

This is the output that I get

..
},
  "aggregations": {
    "text": {
      "value": 32
    }
  }

How can I get the value 32? I am trying the following with no success

response.getAggregations().getValue("text");

This is how I build the query in Java and get the response

  XContentBuilder aggregationBuilder = XContentFactory.jsonBuilder();
        aggregationBuilder.startObject()
               .startObject("query")
               .startObject("match")
               .field("docId", docID)
               .endObject()
               .endObject()
               .startObject("aggs")
               .startObject("text")
               .startObject("max")
               .field("script", "doc['text'].values.size()")
               .endObject()
               .endObject()
               .endObject()
               .endObject();

                SearchResponse response = client.prepareSearch("my_dataset").setTypes("document")
                                        .setSource(aggregationBuilder)
                                        .execute()
                                        .actionGet();

This is the response that I got while debugging enter image description here

See https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/_metrics_aggregations.html

Example:

import org.elasticsearch.search.aggregations.metrics.avg.Avg;
...
Avg avg = searchResponse.getAggregations().get("text");
double value = avg.getValue();

Tested with version 2.3.3.

The solution that worked is

response.getAggregations().get("text").getProperty("value")

getProperty("value") has to be used instead of getValue().

Can you try 

response.getAggregations().get("text").getValue();
