Katalon is not working after upgrading Jenkins from Java 8

After upgrading Jenkins (with Katalon plugin) from Java 8 Katalon is not working. The last line shown (which never been shown before) is

[2022-11-09T14:22:23.457987] Gtk-Message: 14:22:23.457: GtkDialog mapped without a transient parent. This is discouraged.

The older version 8 is still installed and available in /usr/lib/jvm/java-1.8.0-openjdk-amd64

Trying to follow Set a new default JRE for test projects | Katalon Docs

hsn’t helped so far (but perhaps it wasn’t done in the right way).

Please help!

Hi @gdearest07,

Thank you for raising the question. In order to deal with the issue, we might need to clarify the OS you are using:

  • If you are using Linux OS:

Katalon Studio for Linux currently supports OpenJDK 8 only.

We plan to support upgraded JDK in Katalon by Q2 next year. Please keep using the old version until we upgrade it. (Reference)

  • If you are using Window, Mac OS:

This is GtkDialog configuration error. GtkDialog needs transient parent for Gnome developer: gtk - GtkDialog mapped without a transient parent - Stack Overflow.

Please refer to Gnome Docs for more information.

Hope this answer can support this issue. If you need more help, feel free to reach out us. Thank you!
