The supported Java versions depend on your version of Talend Studio.
Java version (OpenJDK or Oracle JDK) | Support type |
---|---|
17 | Supported from R2023-10 onwards |
11 | Supported |
Pay attention to the following before working with Java 17:
- If your Talend Studio has been launched with Java 11, after installing the 8.0 R2023-10 Talend Studio monthly update or a later one, Talend Studio keeps the same behavior as before. You must set the Java interpreter in Talend Studio to Java 8 if you want to execute your Jobs with Java 8. For more information, see Java Interpreter path (Talend).
- After installing the 8.0 R2023-10 Talend Studio monthly update or a later one, if you switch the Java version to 17 and
relaunch your Talend Studio with Java 17:
- To execute your Data Integration Jobs locally in Talend Studio, activate the Enable Java 17 compatibility
option on the view in the Talend Studio
Project Settings dialog box.
If your Jobs include any custom components that require access to the Java internal modules, you need to configure them manually after activating the Enable Java 17 compatibility option. For more information, see Setting up Java in Talend Studio.
Warning: With the Enable Java 17 compatibility option activated, any Job built by Talend Studio cannot be executed with Java 8. For this reason, verify the Java environment on your Job execution servers before activating the option. - To run your Data Integration Jobs on a Remote Engine v2.13 onwards, which
requires Java 17 to start and uses Java 17 by default for execution, you have
two options:
- Rebuild your Jobs: activate the Enable Java 17 compatibility option on the view, following the same process as explained above for running Jobs locally in Talend Studio. This is the recommended approach. This approach allows you to run those Jobs with the default Java 17 version of Talend Remote Engine.
- If you prefer not to rebuild your Jobs, configure the engine to use a different Java version from its default. To do this, specify the Java 8 or 11 instances to be used when installing the engine using the installer, or manually modify a configuration file after the installation.
- To execute your Data Integration Jobs locally in Talend Studio or on a Remote Engine which is running on Java 8, you must set the Java interpreter in Talend Studio to Java 8 and deactivate the Enable Java 17 compatibility option on the view in the Talend Studio Project Settings dialog box. For more information, see Java Interpreter path (Talend) and Setting up Java in Talend Studio.
- To execute your Data Integration Jobs locally in Talend Studio, activate the Enable Java 17 compatibility
option on the view in the Talend Studio
Project Settings dialog box.

The execution of the Big Data Spark Jobs actually depends on the Java versions supported by the cluster.
Java version (OpenJDK or Oracle JDK) | Support type | Notes |
---|---|---|
11 | Recommended | When running Oracle 11, Talend Studio should conform to JDK Compiler Compliance Level 11 (default). |
8 | Supported | When running Oracle 8, Talend Studio should conform to JDK Compiler Compliance Level 1.8 (default). If the installed JDK version is lower than 1.8.0_161, you need to also install the additional resource Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files. This is also applicable to the execution of standalone Jobs. |
