#105 can't start genj on Ubuntu 20.04 LTS with openjdk 11.0.16

[Adam Monsen]

I used genj_install-6755.jar to install GenealogyJ on 64-bit Ubuntu 20.04 LTS desktop. The installer completed successfully.

I'm using the JRE provided by the "default-jre" package. Version info:

openjdk version "11.0.16" 2022-07-19
OpenJDK Runtime Environment (build 11.0.16+8-post-Ubuntu-0ubuntu120.04)
OpenJDK 64-Bit Server VM (build 11.0.16+8-post-Ubuntu-0ubuntu120.04, mixed mode, sharing)

It won't start using run.sh.

The error message is:

I found a workaround. I downloaded genj_app-6865.zip from the "unstable" folder, unzipped it and executed run.sh. That one works well.
