I load the testing openjfx and now I get: (java:4580): Gdk-WARNING **: 10:44:16.937: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.

There's an update to the java11-openjfx package in the testing repo that changes the location. I've pushed another update that allows it to fall back to the old location.

I have the same problem in a new installation.

Still the same problem; help required. Terminal output for /usr/bin/bluej

One more small update, you should now be able to use javafx in projects.

Thanks to the javafx packaging getting sorted out in the repos and the archlinux-java-run script, the latest version should just work™ regardless of what archlinux-java is set to.

It was a problem on my end. The _JAVA_OPTIONS= were set with some weird configs. After I erased it the program started. Hope it helps someone.

Works for me with java-11-openjdk and jdk-11.0.4 from

With java-11-openjdk, however, I cannot run JavaFX applications since JavaFX is not (no longer) included. The error message is: java.lang.NoClassDefFoundError: javafx/appjava.lang.NoClassDefFoundError: javafx/application/Preloader

With the jdk-11.0.4 from JavaFX applications start fine.

Perhaps it would be wise to add no jdk dependencies at all and leave the choice up to the user. In my case, I just extract the jdk from into /usr/lib/jvm, then run 'sudo archlinux-java set jdk-11.0.4' and BlueJ works fully, even with JavaFX applications.

Same as @muesli4. Just get the loading screen and then it hangs.

muesli4 commented on 2019-08-09 21:43

Doesn't work for me. By default I get the same as @hemicepha. When I run:

sudo archlinux-java set java-11-openjdk

I just get the loading screen and nothing happens. It is stuck.
