 - `-DskipTests` is needed for both Spring MVC and WebFlux. This seems to be caused by Mockito.

+- Creating a new `Post` or `Tag` in the `postgres-mvc` project doesn't work. This is a [JHipster bug](https://github.com/jhipster/generator-jhipster/issues/17794) and doesn't seem to be related to Spring Native.
 - Several of JHipster's Administration features don't work: metrics, logs, and configuration.
 - Metrics: `UnsupportedFeatureError: ThreadMXBean methods`
 - Logs: `/management/loggers` returns HTML instead of JSON
