OakSlingRepositoryManager is missing name property for use by RMI and JNDI registries

when I save the RMI configuration in sling 8 the rmi port 1099 starts listening. now in sling 8 it doesn't work. I see the following error in console

"registerRepositroy: Repository not to bew registrated - Service 464 has no name property, nothing to unregister"

When I look for 464 in my instance I find the following service:

[org.apache.sling.jcr.api.SlingRepository, javax.jcr.Repository]

What's wrong? Is there a configuration missing? Is it a bug? Do you can fix it?
