Hi, I'm using ThreadPool to use BulkProcessor like this.

```
final Settings settings = Settings.builder().put(Node.NODE_NAME_SETTING, "high-level-client").build();
final ThreadPool threadPool = new ThreadPool(settings);

//getClient is returning RestHighLevelClient
//listener is BulkProcessor.Listener type

bulkProcessor = new BulkProcessor.Builder(getClient()::bulkAsync, listener, threadPool)
               .setBulkActions(100)

                       ...
               .build();

```

However, If I try to test, there is an exception

```
java.lang.IllegalStateException: Failed to load ApplicationContext
     ...
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'NAME': Invocation of init method failed; nested exception is java.lang.AssertionError
     ...

at java.lang.reflect.Method.invoke(Method.java:498)

```

and CLASS\_NAME.java:100 is

```
final ThreadPool threadPool = new ThreadPool(settings);

```

How can I fix this problem?

I'm using Elasticsearch 5.6.12

I wonder if you have another version of elasticsearch jar somewhere in your classpath...
