I am following spring-native getting started guide.
I can create a spring boot native image which works fine. But as soon as I add DataSource configuration and a few extra dependencies (spring-boot-starter-data-jpa, ojdbc8), even though it works fine from IDE, the native executable does not work.
I tried creating a native docker image as well as a native executable, both are giving the same error as below. I am sure I might be overlooking something.
Error:

Description:
Native reflection configuration for oracle.jdbc.driver.OracleDriver.<init>() is missing.
Action:
Native configuration for a method accessed reflectively is likely missing.
You can try to configure native hints in order to specify it explicitly.
See https://docs.spring.io/spring-native/docs/current/reference/htmlsingle/#native-hints for more details.
I am using sample code same as per documentation: https://github.com/spring-guides/gs-rest-service The only change I have made is in pom.xml and application.yaml. Which are provided as below.
As I mentioned, the application works fine from IntelliJ IDE without any issues. I can build native executable as well as native docker image. But executing them gives me error.

application.yaml
spring:
datasource:
url: "jdbc:oracle:thin:@xx.xx.xx.xxx:1621:xxxx"
driver-class-name: "oracle.jdbc.driver.OracleDriver"
username: "xxxx"
password: "xxxx"
Additional detail if it matters: I am on windows WSL2 Ubuntu
I tried both approaches on the documentation
(1) native image
> mvn spring-boot:build-image
> docker run --rm -p 8080:8080 rest-service-complete:0.0.1-SNAPSHOT
(2) native executable
> mvn -Pnative -DskipTests package
> ./target/rest-service-complete
In both cases, I got the same error.
Updates
To make sure it is not WSL2 issue, I tired later on on linux machine but got same error. I also tried connecting SQLserver with mssql-jdbc driver, same issue, works fine with java -jar but fails when running native-executable.
