KDE/Linux : BROWSE action not supported (Java error)

[bidinou]

Hi ! The default browser is not automatically started on Linux (KDE Neon, based on Ubuntu LTS). I get the usual following error from the Java runtime environment : "java.lang.UnsupportedOperationException: The BROWSE action is not supported on the current platform!"

Apparently, it's due to the problematic Java desktop integration. I could read quite a few testimonies about it, for instance here : https://stackoverflow.com/questions/18004150/desktop-api-is-not-supported-on-the-current-platform

It's not such an issue to manually open the browser but it might give the feeling that the app doesn't work :-) A work-around would be to invoke xdg-open instead from Linux platforms it seems.

Thanks so much for your work & take care !

Thanks for the feedback. If you find a way, I'd happily merge a PR. But as you pointed, this is a minor issue.

Hi!

I had the same issue with another software. It seems that Java relies on gnome to open external links on linux.
I fixed it installing gvfs as reported here: https://wiki.archlinux.org/title/Java#Java_applications_cannot_open_external_links
