"Error while generating citation style"

[wujastyk]

JabRef version

Latest development branch build (please note build date below)

Operating system

GNU / Linux

Details on version and operating system

Linux Mint 21.2 Victoria base: Ubuntu 22.04 jammy

Checked with the latest development build (copy version output from About dialog)

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

JabRef 5.12--2023-11-28--fe07c12
Linux 6.2.0-37-generic amd64
Java 21.0.1
JavaFX 21.0.1+6

1. The Preview tab has stopped working.

2. Going into preferences/entry preview shows that system has broken too:

Hm this is odd. I see that the styles are inlcuded and therefore found. Do you have an example bib entry that doesn't work?

On https://builds.jabref.org/pull/10682/merge (build at #10682), a custom build is available which shows more debugging hints at the output. Could you try?

I've taken that custom build, and I get this error message in the preferences/entry preview/current preview preview window for ACM Materials Journal, the very first citation style.

This error appears for all citation styles with the exception of the default "customized preview style", which displays normally.

org.apache.commons.lang3.CharSet (in module org.apache.commons.lang3) because module org.jabref.merged.module does not read module org.apache.commons.lang3 [in thread "pool-1-thread-2"] at

This seems to be root cause

@wujastyk Thanks a lot for testing, Issue found and fixed here https://builds.jabref.org/pull/10689/merge
A local test with the generated image was working for me here on my mac but would like your feedback as well

[wujastyk]

Yes, that's fixed it. Thank you so much!

JabRef, GitHub, the community - all so great! What a nice world to live in.

JavaFX 22+30

Today's version of JR brings this problem again. All previews are corrupted except the default standard one, which is okay.

[koppor]

@wujastyk Thank you for reporting back so timely. The issue should be fixed in the next build (available in ~30 min at https://builds.jabref.org/main/)

[wujastyk]

Working again. Thanks!
