Talend Data Fabric - Upgrade Notification, Java 17 compatibility for Talend 8 R2024-05 Release

[Katie_Davis]

To our Talend 8 Customers,

To enhance both your security and Talend experience, Java 17 will be the only supported Java version for future updates to Talend Studio and the following supported applications.

• Talend Studio
• Talend Administration Center
• Talend Data Preparation - (client managed installation)
• Talend Data Stewardship - (client managed installation)
• Talend SAP RFC Server
• Talend Semantic Dictionary
• Talend Identity and Access Management

Note: this upgrade does not impact execution of your artifacts that continue to support Java 8 or 11.

Previous versions of Java will no longer be supported by the above application when electing to upgrade to R2024-05. We are giving you this advanced notice to ensure you can plan this upgrade and take time to review your current Java environment. Java 17 support was first introduced with the R2023-10 release.

By giving this advanced notification, we are delighted to be able to reach a point of maturity where we can fully support best practices with dependencies and third-party libraries and be proactive in addressing CVEs to deliver constant improvement to the Talend Studio platform.

Compatibility Documentation:

• For Cloud
• For On Premises
• Artifact for Cloud and Remote Engines

Is it only for data Fabric, what about data management/big data platform ?

Is there a guide on how to migrate from previous Java Versions to Java 17/21? And what to consider while migration? (Local environment, Dev IDE and including the Remote & Runtime Engines as well). 

This seems like a bit of effort, and a Best-Practice or a Guide / Go Through, to not miss anything in production environment would be super helpful. 🙂

Thanks in advance, Best,

Marvin

I asked similar questions on a Talend support ticket recently where the version of Java installed with Talend was flagged as a security issue.

In general it seems like maintaining Java is out of scope for Qlik / Talend support or for being packaged with software updates.

The only way to upgrade Java is to do so manually (including removing the old version if needed) and then update the config file and possibly your desktop shortcut. Apparently no specific testing is required for the upgrade (which surprised me)...

In the support page of Talend, you can not add an environment with Java 17. 

Strangely, I was reverted to this "support portal to raise a case".
