Just trying to play around with ES Java client.
I've cloned https://github.com/elastic/examples/blob/master/Search/recipe_search_java/src/main/java/com/elastic/recipe/IndexRecipesApp.java#L43 and am running the docker image described in https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html#docker-prod-cluster-composefile
(https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html#docker-prod-cluster-composefile + docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:6.6.1
)
When running the example I get an error stating
Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin/java (0x1092354c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x1092b54e0). One of the two will be used. Which one is undefined.

However when I do an insertion via curl everything works.
Can anyone advise what sillyness I'm doing. Google hasn't been particularly helpful.
I've tried turning sniffing on and off, and changing ports amongst other unsuccessful paths.
