As discovered in #912, the issue was first introduced with shared-config 1.5.1 where the native-maven-plugin was upgraded to 0.9.12. Downgrading to 1.5.0 helped address the failure but still need troubleshoot further to see what changed in native-maven-plugin. Still need to keep this issue open.

This is an issue that was recently introduced with native-maven-plugin 0.9.12 where a dependency of type test-jar isn't being included in the classpath that is used with the native-image command: https://github.com/mpeddada1/0.9.12-test-jar

This issue was resolved starting with native-maven-plugin 0.9.14. It was brought in by shared-config 1.5.4. Created follow-up to remove workaround: #1025
