+## Current limitations of Spring Boot's native image build feature
+
+Keep in mind that currently not all Spring modules have built-in support. Therefore, you might need to tell the AOT compiler about the usage of reflection, dynamic proxies etc. There are several ways to deal with these concerns. A good starting point for specifying additional native configuration can be found in the official [Spring documentation](https://docs.spring.io/spring-framework/docs/6.0.0/reference/html/core.html#aot-hints).
