Arch Linux User Repository

Everyone who struggles to update right now: Please install the jdk21-openjdk package. It provides java-environment=21.

@shmilee: I like that idea. Implemented in 5.5-2 using JABREF_OPTIONS as variable name.

Note that you can then also put that environment variable into your .bashrc, .pam_environment or something similar to be automatically applied.

How about add an extra JavaOptions variable in launch script /usr/bin/jabref like this?

............
--module-path ${ROOT}/lib \
${JABREF_EXT_Options} \
--patch-module .............

So we can add the -Djdk.gtk.version=2 flag or -Dglass.gtk.uiScale=144dpi flag by cmdline, no need to edit /usr/bin/jabref after upgrade.

JABREF_EXT_Options='-Dglass.gtk.uiScale=144dpi -Djdk.gtk.version=2' jabref

Using JabRef with i3wm, I’m running into the issue described at https://github.com/JabRef/jabref/issues/5867 in which clicking the menu bar sometimes opens then immediately closes the associated menu, rendering it unusable.

I was able to fix this issue by adding the -Djdk.gtk.version=2 flag after line 9 in https://aur.archlinux.org/cgit/aur.git/tree/jabref.sh?h=jabref (as suggested in the related bug report https://bugs.openjdk.java.net/browse/JDK-8251240). This change also removes the “XSetErrorHandler() called with a GDK error trap pushed. Don't do that.” warning mentioned by ruiin in a previous comment.

So far, I have not encountered any adverse side-effect from this workaround.

I've "resolved" it by replacing

toolchain {
    languageVersion = JavaLanguageVersion.of(20)
}

with

toolchain {
    languageVersion = JavaLanguageVersion.of(21)
}

in build.gradle. It seems that JabRef requires exactly JDK20 to compile, however Arch Linux doesn't provide any package containing version 20 of JDK anymore.

@Bevan these are the outputs. archlinux-java status:

Available Java environments:
  java-11-openjdk
  java-17-openjdk
  java-21-openjdk
  java-8-openjdk/jre (default)

archlinux-java-run -a 20 -f jdk -j:

/usr/lib/jvm/java-21-openjdk

@carlosal1015: I tried with Java 17 and while building the package works, launching JabRef does not. So I think at least version 20 is required.

@Pavlov and @vanja_z: I could not reproduce your issue yet. Can you please post the output of the following commands?

• archlinux-java status
• archlinux-java-run -a 20 -f jdk -j

Hi, is mandatory java-runtime>=20 or could be relaxed until 17?

Even with archlinux-java-run=10-1 the problem persists:

Execution failed for task ':compileJava'.
> Error while evaluating property 'javaCompiler' of task ':compileJava'.
   > Failed to calculate the value of task ':compileJava' property 'javaCompiler'.

Sorry, I missed to update archlinux-java-run in time for JDK 21 which caused issues with building or running Java applications that use it. Please update archlinux-java-run to v10 and report back if there are still any issues afterwards.

Nice, thanks for the quick update!

Luckily, that JDK 21 requirement is only due to a bug in jlink, which we do not use when building JabRef. So, updating to 5.10 is possible with JDK 20.

5.10 seems to require OpenJDK 21 which is not yet released.
