Add AOT repository support.

christophstrobl · christophstrobl · commit 1bfc3595ce2e · 2022-07-06T15:16:41.000+02:00
We now use the AOT infrastructure of Spring Framework 6 and data commons to provide AOT support building the foundation for native image compilation. Additionally we register hints for GraalVM native image. Also update jpa auditing configuration to avoid inner bean definitions. See: #2497 Original Pull Request: #2588
