Hello everyone,

We need to migrate some code from the current Java High Level REST Client (HLRC) to the new Java API Client 7.7.15.

I have this snippet of Kotlin code I need to rewrite using the new Java Client API:

```auto
val lockObject = lockObject(
    lockConfiguration.name,
    lockConfiguration.lockAtMostUntil,
    now()
)

val ur = UpdateRequest()
    .index(index)
    .id(lockConfiguration.name)
    .script(
        Script(
             ScriptType.INLINE,
             "painless",
             UPDATE_SCRIPT,
             lockObject
         )
     )
     .upsert(lockObject)
     .setRefreshPolicy(WriteRequest.RefreshPolicy.IMMEDIATE)
     val res = highLevelClient.update(ur, RequestOptions.DEFAULT)
     res.result != DocWriteResponse.Result.NOOP

```

Based on the [example mentioned here](https://discuss.elastic.co/t/how-to-update-a-single-field-using-the-java-api-client/306679), I have tried to come up with something, but it still does not look right to me, because:

- I am not sure, how the .script() part need to be rewritten
- I don't know how to handle the refresh policy in the new client code

Here's the code:

```auto
val response = client.update({ u: UpdateRequest.Builder<LockConfiguration, Map<String,Any>> ->
                    u.index(index).id(lockConfiguration.name).doc(lockObject) }, LockConfiguration::class.java)

```

Is there anyone who could contribute an example here doing such an update operation?

Thank you very much for your help

Best regards,  
André

@swallez Could you maybe provide an example or some access to preliminary documentation on this one? Thank you very much!
