Hi, I heard that there are stability issues with running Oracle Java 1.7 update 45 and 0.90 ES versions. Does anyone know the details of this issue ? It would be useful if ES team could publish the recommended Oracle Java version to use and the reasons behind it.

Hi, Indeed Lucene suffers from bugs in Oracle's Java 1.7u40 and 1.7u45. However, 1.7u25 should be safe. You can find information about these bugs in Lucene's JIRA and mailing-list. For example, here is one that affects Java 1.7u40: [https://issues.apache.org/jira/browse/LUCENE-5212](https://issues.apache.org/jira/browse/LUCENE-5212) -- Adrien Grand -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
