Qlik Talend Studio: Job fails with error "Unrecognized option: --add-opens"

wei_guo · May 14, 2024 6:00:47 AM

A Job fails to run on a remote JobServer with the following error message:

Unrecognized option: --add-opens=java.base/java.lang=ALL-UNNAMED
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Cause

The issue occurs with Talend Remote Engine or Talend JobServer using Java 8, but Talend Studio has JDK 17 enabled. The --add-opens option is only supported in java 11 and above, Java 8 does not support it.

If the 'Enable Java 17 compatibility' option is enabled, the Jobs built by Talend Studio will have the --add-opens parameters in the job.sh or job.bat script files, such as:

JAVA_OPTS=-Dfile.encoding=UTF-8 -Dsun.stdout.encoding=UTF-8 -Dsun.stderr.encoding=UTF-8 -Dconsole.encoding=UTF-8 --add-opens=java.base/java.lang=ALL-UNNAMED

The Jobs built this way cannot be executed with Java 8.

Resolution

Option 1:

Click on the toolbar of Talend Studio main window, or click File > Edit Project Properties from the menu bar to open the Project Settings dialog box.
Expand the Build node and click Java Version to open the corresponding view.
Deactivate the 'Enable Java 17 compatibility' option.
Re-build the Job and re-publish it to Talend Remote Engine or Talend JobServer.

Option 2:

From R2024-05, Java 17 will become the only supported version to start most Talend modules, If you want to keep the "Enable JAVA 17 Compatibility" option enabled, make sure that Talend Remote Engine or Talend JobServer also uses JDK 17 to execute jobs.
