>             Project: Hibernate ORM

>          Components: core
>    Affects Versions: 4.1.0

> Due to the work done for HHH-6974 inserting an @Immutable entity with a @NaturalId results in a NullPointerException
> The cause appears to be due to read-only entities not having EntityEntry.getLoadedState() populated upon insert and StatefulPersistenceContext.getNaturalIdValues assumes that array will not be null.
