When trying out https://github.com/vaadin/hilla and https://github.com/vaadin/flow together with the native support in Spring Boot 3, I ran into an issue on startup:

The code in VaadinServletContextInitializer.java:191 is

throw new RuntimeException(

and the exception it catches is

The flow-server.jar has resources in com/vaadin/flow/component, com/vaadin/flow/router and com/vaadin/flow/server and to make testing easier I included
hints.resources().registerPattern("com/vaadin/flow/*");
in a RuntimeHintsRegistrar and this seems to trigger the problem. If I restrict the pattern to com/vaadin/flow/server/* then I do not see the problem. Probably because the mentioned class com/vaadin/flow/router/AfterNavigationEvent.class is not included as a resource

@Artur- thanks for the report, I believe this could have been a duplicate of #29397 but you're already using the version with that fix. We'll have another look.
Comment From: Artur-
I believe I am using Spring 6.0.0-RC2 and the fix is marked for 6.0.0-RC3?
Comment From: snicoll
Indeed, sorry. It might be a duplicate after all. Can you please try with either 3.0.0-SNAPSHOT or by setting spring-framework.version to 6.0.0-RC3?
Comment From: Artur-
Using <spring-framework.version>6.0.0-RC3</spring-framework.version> indeed seems to solve this problem, thanks.
I do run into other errors about missing classes but those are probably my fault
Comment From: snicoll
Thanks for checking and reporting back.
