The problem is that Log4j2 is simply not compatible with Java 9. I’ve created a very simple Java 9 application which shows this problem: https://github.com/tobiasdiez/javatestbed. Currently, I’m in contact with the log4j devs to solve this problem. Luckily the consequences for JabRef are not that negative - the only functionality that does not work because of this issue is the “error console” and errors are only written to the command line.

the version from 2019-08-25 didnot show the console. What has changed inbetween?
