 #### JDK 11
 
-OpenSearch builds using Java 11 at a minimum, using the Adoptium distribution. This means you must have a JDK 11 installed with the environment variable `JAVA_HOME` referencing the path to Java home for your JDK 11 installation, e.g. `JAVA_HOME=/usr/lib/jvm/jdk-11`. This is configured in [buildSrc/build.gradle](buildSrc/build.gradle) and [distribution/tools/java-version-checker/build.gradle](distribution/tools/java-version-checker/build.gradle).

-#### JDK 14
+Since 8.10 release, Gradle has deprecated the usage of the JDKs below JDK-16. As such, for development purposes we recommend to install additionally at least [JDK 17](https://adoptium.net/temurin/releases/?version=17) or [JDK 21](https://adoptium.net/temurin/releases/?version=21). If you still want to stick to JDK-11 only, please add `-Dorg.gradle.warning.mode=none` when invoking any Gradle build task from command line, for example:
 
-To run the full suite of tests, download and install [JDK 14](https://jdk.java.net/archive/) and set `JAVA11_HOME`, and `JAVA14_HOME`. They are required by the [backwards compatibility test](./TESTING.md#testing-backwards-compatibility).
