Hi,
I installed elasticsearch 6.2.1 (also tried 6.1.2) on my mac, and I am getting various exceptions due to Java security issues.
Searching google I found very few suggestions, all of them pointing to the Java policy file, which to me seems correctly defined. A colleague of mine installed the same version on a similar setup (his mac), and it is running without issues.
When running 6.2.1 I got the following exceptions:
java.security.policy : erreur d'ajout d'entrée :
java.net.MalformedURLException: no protocol: ${codebase.netty-common}
java.security.policy : erreur d'ajout d'entrée :
