Arch Linux User Repository

Currently doesnt seem to work with java 21 (archlinux-java set java21-openjdk) and java21-openjfx-bin I always get

Error occurred during initialization of boot layer
java.lang.module.FindException: Module javafx.web not found

Part of the PKGBUILD file (not the whole!) which downloads latest and sets version of the package to git's hash:

pkgver() {
  printf "r%s.%s" "$(git rev-list --count HEAD)" "$(git rev-parse --short HEAD)"
}

I see. Openjfx being removed was the reason why I assumed 17 is the most recent version of it. I'm trying to use 21 now.

I also tried java-openjfx-bin instead of java-openjfx from AUR to skip the compiling, but with this I got the old error:

[rawjaw@ws2 ~]$ miniongg

The package still works as-is with the latest version of OpenJDK and OpenJFX. Previously I've received feedback that forcing users to install a particular version of Java is not a good idea.

$ pacman -Qi java-runtime
Name            : jdk-openjdk
Version         : 21.u35-8
$ pacman -Qi java-openjfx
Name            : java-openjfx
Version         : 21.0.1.u6-1
$ archlinux-java get
java-21-openjdk

With this configuration, Minion launches fine with the current PKGBUILD.

OpenJFX is unfortunately no longer in the [extra] repository, so it has to be built from source as an AUR package. Building java-openjfx is very memory-intensive (on my 16c32t system it used about 30 GiB), however there are instructions in the AUR comments for java-openjfx that provide guidance on how to lower the parallelism for CMake to reduce the memory footprint of the compilation process.

Can I get co-maintainer on this? I've got a few ideas for fixes.

I looked into this more closely and saw that /usr/bin/miniongg (installed by this package) is actually a shell script that relies on java modules in /usr/lib/jvm/default. This explains why java 17 must be set as default in order to work properly with this script

My suggestion would be to make jre17-openjdk a dependency of miniongg and to change the module paths in /usr/bin/miniongg from /usr/lib/jvm/default to /usr/lib/jvm/java-17-openjdk. This would take away the possibility to chose which version of java to use to run minion, but as minion only runs with java 17 there is no choice anyway. For the most common setup (using the most recent java version as the system default), this package is broken.

In the .sh file, you could prepend JAVA_HOME=/usr/lib/jvm/java-17-openjdk to the java command, if your intention is to pin it to a certain jvm. This way it will run no matter which java is the system default, but it erodes user choice. Some people might want to run a different flavor of the JRE like temurin, zulu, etc.

I figured out that minion only runs with openjdk 17. I think it's because it requires java-openjfx of which the most recent version is also 17 so you can't run minion with java 21.

However, one thing seems odd: I need to set java 17 as the system default for minon to work, just calling it using java 17 while having set java 21 as default does not work.

Examples:

[rawjaw@ws2 ~]$ export PATH="/usr/lib/jvm/java-17-openjdk/bin/:$PATH"
[rawjaw@ws2 ~]$ java --version
openjdk 17.0.9 2023-10-17
OpenJDK Runtime Environment (build 17.0.9+8)
OpenJDK 64-Bit Server VM (build 17.0.9+8, mixed mode)
[rawjaw@ws2 ~]$ miniongg

java.lang.module.FindException: Module javafx.web not found
[rawjaw@ws2 ~]$

[root@ws2 rawjaw]# archlinux-java set java-17-openjdk
[rawjaw@ws2 ~]$ miniongg
-> minion runs fine.

Does not run anymore. All dependencies are met.

@kruzah, Thank you, setting the default java version to 19 fixed everything. java-openjfx was automatically installed as a dependency. No need to keep java 8 around and therefore no more python2 required.

It's a bit of a pitfall that you can only set the default java version to a fixed version and not make the most recent the default automatically. If you barely use java and don't care about it, you might get stuck on a years old version unwittingly and some day it will cause problems.
