NullPointerException in RestConfiguration

[jdebouil]

Describe the bug
After migrating from spring-content 2.4.0 to 2.7.0 I experiment NPE when starting Spring Boot Application

Screenshots

Additional context
According to source code :

 @Bean
    MappingContext mappingContext() {
        MappingContext context = new MappingContext("/", ".");

        for (StoreInfo info : stores.getStores(Stores.MATCH_ALL)) {
            if (info.getDomainObjectClass() != null) {
                context.getContentProperties(info.getDomainObjectClass());
            }
        }

        return context;
    }

May be you should inject the stores by type/name ?

MappingContext mappingContext(Stores stores) {
...
}
