Same issue as in: spring-projects/spring-data-mongodb#4237

Reproducer: https://github.com/micheljung/spring-data-keyvalue-569

@SpringBootApplication
@EnableMapRepositories
class DemoApplication

fun main(args: Array<String>) {
    val context = runApplication<DemoApplication>(*args)
}

interface WebsiteRepository : CrudRepository<Website, String>

@KeySpace("website")
data class Website(
    @Id
    val id: String,
    val url: URL,
)

Output:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'websiteRepository' defined in com.example.demo.WebsiteRepository defined in @EnableMapRepositories declared on DemoApplication: Unable to make field private java.lang.String java.net.URL.protocol accessible: module java.base does not "opens java.net" to unnamed module @139982de
