The current ES docs reference Java 7 u60: [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/\_installation.html#\_installation](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/_installation.html#_installation) Lucene seems to just say u55 or higher: [http://lucene.apache.org/core/4\_9\_0/SYSTEM\_REQUIREMENTS.html](http://lucene.apache.org/core/4_9_0/SYSTEM_REQUIREMENTS.html) Has anyone used/verified ES with OpenJDK 7u65? The push for upgrading is coming from this security update: [https://lists.debian.org/debian-security-announce/2014/msg00169.html](https://lists.debian.org/debian-security-announce/2014/msg00169.html) Thanks -Greg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Do not use Java 7u65. It breaks Google Guava (used by Elasticsearch) and also Groovy (which is planned for ES 1.4 being the default), and maybe more.
