Hi.  
I'm using the Elasticseach Rest high-level client 6.3.2 in Grails/Groovy project.  
Here is the Gradle dependecy I have added as suggested in the documentation [[https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.3/java-rest-high-getting-started-maven.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.3/java-rest-high-getting-started-maven.html)] :  
dependencies {  
compile 'org.elasticsearch.client:elasticsearch-rest-high-level-client:6.3.2'  
}

Now, even if I have just the import statement at the beginning of the service file without any body in the service class, starting Grails will always throws the below error. If I comment out the import statements the Grails app starts perfectly alright.

The import statement I used:  
import org.elasticsearch.ElasticsearchException

The error I get is:  
Sep 12, 2018 2:22:48 PM org.springsource.loaded.agent.SpringLoadedPreProcessor preProcess  
SEVERE: Unexpected problem transforming call sites  
java.lang.IllegalStateException: Unexpected problem processing bytes for class

Can someone help me out of this?

Thanks.
