Resource location does not end with slash

[ecabrera78]

I migrated an application from spring-boot 3.3.6 to 3.4.2. We have below code to create a static resource locator:

@Bean
RouterFunction staticResourceLocator() {
  return RouterFunctions.resources("/**", new FileSystemResource("/opt/cfg/static/"));
}

After the migration this code is throwing an exception:
Failed to instantiate [org.springframewok.we.reactive.function.server.RouterFunction]: Factory method 'stticResourceLocator' threw exception with message: Resource location does not end with slash: /opt/cfg/static

I found that when FileSystemResource is created there is a call to StringUtils.cleanPath(path) where the last slash is removed from the original path.

is there another way to create the FileSystemResource and preserve the last slash?
