title: Java Runtime Engine support for SonarQube 7.x
body: <p>On the SonarQube <a href="https://docs.sonarqube.org/display/SONAR/Requirements" rel="nofollow noreferrer">requirements</a> page you can read that JRE 8 is a requirement and newer Java runtime versions are not supported. Looking at the <a href="http://www.oracle.com/technetwork/java/eol-135779.html" rel="nofollow noreferrer">Oracle Java SE Support Roadmap</a> the public update support for version 8 could be stopped on January 2019. Does anyone know how Sonarsource will update their JRE usage (web application, plugins and scanner) in the coming period?</p>
  
  <p><strong>Update (07-06-2018)</strong>
  Jira item SONAR-10574 describes the upgrade of Elasticsearch to 5.6.8 in a 7.x version although looking at the <a href="https://www.elastic.co/guide/en/elasticsearch/reference/5.6/es-release-notes.html" rel="nofollow noreferrer">ElasticSearch release notes</a> version 5.6.9 already exists. Support of Java 9 is added in ElasticSearch 6.2 and support for <a href="https://discuss.elastic.co/t/does-elasticsearch-support-java-10/134763" rel="nofollow noreferrer">Java 10 will be added in 6.3</a>. See also <a href="https://www.elastic.co/blog/elasticsearch-java-9-and-beyond" rel="nofollow noreferrer">this</a> article in which the ElasticSearch future plans are described. Will SonarQube only support the Java LTS versions?</p>
  
  <p><strong>Update (19-08-2018)</strong>
  Issue SONAR-10574 is removed from Jira. Found <a href="https://www.elastic.co/support/matrix#matrix_jvm" rel="nofollow noreferrer">this</a> support matrix regarding the Java versions supported by ElasticSearch. SonarQube still uses ElasticSearch 5.6.3.</p>
