Description

I am using below stack to index a data into Elasticsearch using Camel Elasticsearch component:

• Elasticsearch 7.15.0
• Apache Camel 3.12.0
• Spring 5.3.12
• Spring Boot 2.5.6

While indexing the data into Elasticsearch 7.15.0, I am getting ClassNotFoundException: org.elasticsearch.common.CheckedConsumer

please have a look on the detailed error below:

I investigated the issue in details and came to know that package org.elasticsearch.common.CheckedConsumer is present in elasticsearch-core-7.13.0.jar but the common package is completely missing in elasticsearch-core-7.15.0.jar. This is why while talking with Elasticsearch using Apache Camel component we are getting this runtime error.

Please have a look on the attached images for the package structure and class information in respective jars.
