Updating this old thread as @monde shared with me a solution he found on [SOF](https://stackoverflow.com/questions/34889026/how-to-use-the-elasticsearch-java-api-to-build-an-aggregation-from-json):

```
 val aggsRequestBuilder = new SearchRequestBuilder(client)
  .setIndices(index())
  .setQuery(QueryBuilders.wrapperQuery(query.toString())
  .setAggregations(agg.toString().getBytes())
```
