JSON document malformed when indexed with bulk operation

[tryge]

The following request:

Bulk bulk = new Bulk.Builder()
            .defaultIndex(Constants.RECIPE_INDEX)
            .defaultType(Constants.RECIPE_TYPE)
            .addAction(
                new Index.Builder("{\"test\":\"with sensible whitespace in a document\"}").id("1").build()
            ).build();

yields the following document as result

{"test":"withsensiblewhitespaceinadocument"}
