ElasticSearch java.lang.IllegalStateException: jar hell
Try to use:
-Dtests.jarhell.check=falseRemark: It works with my Elasticsearch 2.4. I saw comments, that it is not available in all Elasticsearch versions (see Elasticsearch jar hell when writing integration tests)
I got the same error message with catalina.jar conflicting with catalina-ant.jar. So, the quick fix was to rename catalina-ant.jar to catalina-ant.jar.orig in the $TOMCAT/lib folder.
Tomcat is still running for me, even with the one library missing.
