Unexpected problem processing bytes for class in Grails with Elasticsearch

Question

I'm trying to get Elasticsearch working in my Grails project. I'm using the Java Rest High-level client in Elasticsearch documented here [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/6.3/java-rest-high-getting-started-maven.html]. I'm using Elasticsearch 6.3.2 version, Java 8, Grails 2.4.4

I have created a service class and added an import statement at the beginning of the file. For eg: import org.elasticsearch.ElasticsearchException And, when I start Grails I get the error below. But if I remove that import statement the application runs fine. So, what's happening in the import ?

So, can someone help me understand what's happening here?

Thanks.

I got this error in versions of Java later than Java 7, but was able to get it to work in Java 7
