I know the guide says the following: While a JRE can be used for the Elasticsearch service, due to its use of a client VM (as oppose to a server JVM which offers better performance for long-running applications) its usage is discouraged and a warning will be issued. But I noticed something on oracles page called the Server JRE. Does anyone know if this is equivalent to the server JVM at runtime?

Yes, you can use Java Server JRE. It is a build without Java desktop graphics library (aka headless JVM).
