Using @Version gives error - version_type parameter value must be lowercase

Elasticsearch expects version_type parameter value to be lowercase (case-sensitive), i.e. it should be “external”, not EXTERNAL. Gives error with ES 2.3 (and 2.4). Tested with AWS ES service and standalone.

Given:

@Document(indexName = "version-test")
public class MyDoc {
  ...
  @Version
  private Long version = 0L;
}

When: saving to index (using an ElasticsearchRepository)

Then:

2016-09-16 03:45:18.451 ERROR 68586 --- [           main] c.g.v.s.jest.JestElasticsearchTemplate   : Cannot execute jest action , response code : 400 , error : {"root_cause":[{"type":"illegal_argument_exception","reason":"No version type match [EXTERNAL]"}],"type":"illegal_argument_exception","reason":"No version type match [EXTERNAL]"} , message : null

---

Suggestion: see JestElasticsearchTemplate.java Line 1165 - convert to lowercase string (or use ordinal).

            if (query.getVersion() != null) {
                indexBuilder.setParameter(Parameters.VERSION, query.getVersion());
                indexBuilder.setParameter(Parameters.VERSION_TYPE, EXTERNAL);
            }

Yes, the current master works on my env now with Spring Boot 1.4 + ES 2.4 (embedded). Thank you!

Thanks @VanRoy I think I missed your upgrade. I will test my system now. If it works.

Thanks Ruchi
