Compatible Java Environments
The following tables provide information on the recommended Java Environment to use with your Talend product from February 2025 and later. If you are using Talend 8.0 products that were not patched nor updated with the February 2025 updates or later ones, see Compatible Java Environment before February 2025.
The supported Java platforms are OpenJDK and Oracle JDK. The recommended distribution for OpenJDK is Zulu.
In the following documentation:
- Recommended: designates an environment recommended by Qlik based on experience and customer usage.
- Supported: designates a supported environment for use with the listed component or service.
- Supported with limitations: designates an environment that is supported by Qlik but with certain conditions explained in notes.

Supported Java versions for running Talend artifacts
- Data integration Jobs and Routes are compiled with Java 17.
- Big Data Jobs are compiled with Java 8 with the add-opens parameters automatically included. Therefore, they can be executed with Java 17 in Talend modules, and with Java 8 in a big data cluster. In other words, the Job is launched with Java 17, then deployed in the cluster that runs in Java 8.
The following table shows in which Java environments the corresponding item can be executed:
Java version for execution | Support type |
---|---|
17 | Supported Note that Routines compliance can be set up to Java 8 or 17. |
Java version for execution | Support type |

Java version for execution | Support type |

The execution of the Big Data Spark Jobs actually depends on the Java versions supported by the cluster.
