@chetgurevitch Thank you for your quick reply and help. Unfortunately, I couldn't figure out anything I could install additionally or change. I posted the output of

$ pacman -Fl java11-openjfx on https://pastebin.com/DzGu8qJ3

and $ archlinux-java status results in

java-11-openjdk java-12-jdk (default) java-13-openjdk java-8-jre/jre

(as written in my first post)

The installed Bluej-Version is 4.2.2-1.

Appreciate your help!

@chromanju can't reproduce, make sure you're using the latest PKGBUILDs (4.2.1-5 and 3.6.0-3), you have java11-openjfx installed, and your system is fully up to date. If you're still experiencing the issue please post the output of

$ pacman -Fl java11-openjfx

and

$ archlinux-java status

edit: about to update bluej to 4.2.2, would be best if you could test with this version

BlueJ still won't start resulting in these error(s); help required: xception in thread "main" java.lang.NoClassDefFoundError: javafx/application/Application at java.base/java.lang.ClassLoader.defineClass1(Native Method) at java.base/java.lang.ClassLoader.defineClass(ClassLoader.java:1016) at java.base/java.security.SecureClassLoader.defineClass(SecureClassLoader.java:151) at java.base/jdk.internal.loader.BuiltinClassLoader.defineClass(BuiltinClassLoader.java:802)

Bluej gets stuck in loading screen and is not responding when I try to open it. I had bluej installed before the 3 latest updates, where it worked fine.

Terminal output: (java:10299): Gdk-WARNING **: 10:34:56.196: XSetErrorHandler() called with a GDK error trap pushed. Don't do that.

Edit: Never mind. You just need to smash some random keys, when it is stuck on loading screen for bluej to open.

this tries to install java11-openjfx which conflicts then with java-openjfx-bin which already provides java-openjfx=11.0.2

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.

gurevitch commented on 2019-08-22 01:03 (UTC)

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.

ThomasKl commented on 2019-08-21 10:46 (UTC)

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.
