Hello, I am running into a conflict with Solr and ElasticSearch. We are trying to add support for Elastic Search 5.1.1 which requires Lucene 6.3.0 to an existing system that uses Solr 5.2.3. At the moment I am using SolrJ 5.3.1 to talk to the 5.2.3 Server. I was hoping I could just update the SolrJ libraries to 6.3.0 so the Lucene conflict goes away, but when I try to run my unit tests I'm seeing this error:
