While Iced Tea OpenJDK 8 may work fine (and many users are using it), it is not currently considered an officially supported Java version.\r\n\r\nThe way the documentation is written today (https://www.elastic.co/guide/en/elasticsearch/reference/2.3/setup.html#jvm-version) can be a bit misleading.\r\n\r\n>Elasticsearch is built using Java, and requires at least Java 7 in order to run. Only Oracle’s Java and the OpenJDK are supported. The same JVM version should be used on all Elasticsearch nodes and clients.\r\n>We recommend installing the Java 8 update 20 or later, or Java 7 update 55 or later. Previous versions of Java 7 are known to have bugs that can cause index corruption and data loss. Elasticsearch will refuse to start if a known-bad version of Java is used. \r\n\r\nSo let's update the documentation to cross reference the https://www.elastic.co/support/matrix#show_jvm instead :)\r\n\r\n"}}
