I have elasticsearch 5.2.0 with x-pack. I am in OS X Sierra and I downloaded the binaries from the official website
An exception shows up everytime I try to start elasticsearch. The Warning shown is the following:

Do you know what is it and why does it appear and how to make it stop? N.B.: Elasticsearch correctly start after this warning, and everything seems to work fine (for example in querying it or adding indexes and elements to them), but it bothers me that warning and I am afraid that it is a sign for something worse. Thank you in advance
