I want to create a runtime field based on some conditions. And i have a query which is working fine on kibana console. I implemented the same query on java code but is not working. There is a method in SearchRequest `runtimeMappings()` which is overloaded and can accepts `String key, List<RuntimeField> value` or can accepts `Map<String, List<RuntimeField>> map` . But when I am using any of these methods and running my query, it is throwing an exception: `Caused by: org.elasticsearch.index.mapper.MapperParsingException: Expected map for runtime field [w_ticket_category] definition but got a java.util.ArrayList`. This is happening because the ES expects `Map` instead of `List` in the value of these mathods. The query on kibana console taking value as a `Map` only and is working, and if I am trying to pass a `List` instead of `Map` then I am getting the same error.

UPDATE: I got a diff in which we can see the changes for that method. The `runtimeMappings(String key, RuntimeField value)` changed to `runtimeMappings(String key, List<RuntimeField> value)` and similarly `runtimeMappings(Map<String, RuntimeField> map)` changed to `runtimeMappings(Map<String, List<RuntimeField>> map)`.  
Is there any specific reason for it.  
[Github Diff Link](https://github.com/elastic/elasticsearch-java/commit/7444423055b1826b147a1c104d96793aee5281f8#diff-3ba9b5684e7ba0055f11a4351fa5bacd8c2632c346f95f45dad8c6c6b094cc12)  
Is it known issue or i'm doing something wrong...  
Any help would be appreciated.  
Thanks
