That's excellent news, thank you!

Let me try ...

During build I see some scary output:

Malformed class file [module-info.class] in jar [/usr/share/maven-repo/org/apache/logging/log4j/log4j-api/debian/log4j-api-debian.jar] found on classpath, which means that this class will cause a compile error if referenced in a source file. Gradle 5.0 will no longer allow malformed classes on compile classpath.

but the build finishes.

At runtime, I see no single warning related to log4j, and jabref just
starts - yay \o/
