Wrong usage of beanDefinition.getBeanClassName()

[itineric]

Starting from spring 6.0.11, existing code in this library may not work anymore. Some spring @Bean annotated with @Provider and other Jakarta-RS annotations are not recognized anymore (since getBeanClassName() is null) and are not registered in Resteasy as it was with srping version 6.0.10 and previous versions.

In the following class: https://github.com/resteasy/resteasy-spring/blob/main/resteasy-spring/src/main/java/org/jboss/resteasy/plugins/spring/SpringBeanProcessor.java , the calls to BeanDefinition.getBeanClassName() should be BeanDefinition.getResolvableType().toClass()

See: spring-projects/spring-framework#31242 (comment)

@itineric thanks for notifying this! I'll create PR for this.

@itineric I tried to replace the method however I got the null pointer exception. Could you please provide a working PR for this?

To provide a bit more context, the existing code is using low-level code of the core container that it shouldn't. If you need to get the type of a bean beanFactory#getType(String beanName) is what you should be calling. I believe that static Bean method are not working either (with a recent or an older Spring release).

Sorry I have been dragged to other tasks for the last months, I'll come back to this issue then.
