Native build is broken?

[anthonydahanne]

• checkout main branch
• use Java 21
• do a native build with:

./mvnw  -Pbuildpacks-native

• start the container

docker run -it -p 8080:8080 restbucks:1.0.0-SNAPSHOT

• do a POST request

POST http://localhost:8080/orders
Content-Type: application/json

{
  "location": "To go"
}

You'll get 500 with:

13:50:00.280 I -     main : Started Restbucks in 0.385 seconds (process running for 0.393)
13:50:02.678 I - andler-0 : Initializing Spring DispatcherServlet 'dispatcherServlet'

Hint

It's possible there's missing metadata (or incompatible classes)for the native compilation; playing around with the app, I also got:

13:41:35.805 E - andler-2 : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed: org.springframework.aop.framework.AopConfigException: Could not generate CGLIB subclass of class org.springsource.restbucks.drinks.Drink: Common causes of this problem include using a final class or a non-visible class] with root cause

[anthonydahanne]

also had

13:57:29.771 I - andler-0 : Completed initialization in 0 ms
13:57:37.963 I - andler-1 : Couldn't read class metadata for interface org.springsource.restbucks.order.OrderProjection. Input property calculation might fail

[anthonydahanne]

it's possible that the Rest API does not handle the error cases very well, hence some 500

Http failure response for http://localhost:8080/orders/search/findByStatus?status=jjj: 500 OK
