 #### Java
 
-Use Java 11 for Jenkins jobs CI. This means you must have a JDK 11 installed with the environment variable `JAVA_HOME` referencing the path to Java home for your JDK installation, e.g. `JAVA_HOME=/usr/lib/jvm/jdk-11`. Download Java 11 from [here](https://adoptium.net/releases.html?variant=openjdk11).
+Use Java 17 for running Jenkins CI tests. Ensure that JDK 17 is installed on your system and that the `JAVA_HOME` environment variable is correctly set to the JDK 17 installation path.
