[[supported-platforms]]
[discrete]
== Supported platforms
The matrix of officially supported operating systems and JVMs is available here:
link:/support/matrix[Support Matrix]. Elasticsearch is tested on the listed
platforms, but it is possible that it will work on other platforms too.
[discrete]
[[jvm-version]]
== Java (JVM) Version
Elasticsearch is built using Java, and includes a bundled version of
https://openjdk.java.net[OpenJDK] from the JDK maintainers (GPLv2+CE)
within each distribution. The bundled JVM is the recommended JVM and
is located within the `jdk` directory of the Elasticsearch home directory.
WARNING: The bundled JVM requires glibc 2.14+. CentoOS 6 and Oracle Enterprise Linux 6
have an outdated version of glibc, so on those platforms you must use your
own version of Java, version 14 or older.
To use your own version of Java, set the `JAVA_HOME` environment variable.
If you must use a version of Java that is different from the bundled JVM,
we recommend using a link:/support/matrix[supported]
https://www.oracle.com/technetwork/java/eol-135779.html[LTS version of Java].
Elasticsearch will refuse to start if a known-bad version of Java is used.
The bundled JVM directory may be removed when using your own JVM.
