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 https://bell-sw.com/.

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 https://bell-sw.com/ 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 https://bell-sw.com/ 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.

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.

I guess the first 2 lines in bluej execute are inappropriate. Because "archlinux-java get" will get the name of default JRE/JDK folder directly, there is no need to get the major version number of currently installed java lib.

The jdk-openjdk package contains the java-12-openjdk version and it looks like bluej can't use it yet:

You have to manually install jdk11-openjdk and set it as default sudo archlinux-java set java-11-openjdk

[SOLVED] For solving the java version problem you must have installed the jdk-openjdk package and run:

sudo archlinux-java set java-11-openjdk

I tried 4.2.0 and 4.2.1 both didn't work. I installed openjfx and all java stuff but i am getting this error: Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.UnsupportedClassVersionError: bluej/Boot has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Edit: With the command above it just works fine. Thank you for your help.

@Fuxy you need java-openjfx-bin from the aur.

@auslaander did you make sure jdk11 was the default with archlinux-java?

If you did and it still didn't work could you try running bluej from the terminal and attach the output?
