MappingException when @MapKeyColumn refers to a column mapped in embeddable map value

Description

Map<Basic, Embeddable> does not work, when the map key is a persistent field of the value. The map key shall not be represented as a separate table column, this is why the example uses @MapKey and not @MapKeyColumn.

Example:

Hibernate appears to expect an Entity as map value:

org.hibernate.AnnotationException: Associated class not found: LocalizedString

Pardon me, but this doesn't appear to be fixed.

Here's a problem description from 2018: https://stackoverflow.com/questions/49940382/annotationexception-when-mapkey-refers-to-a-column-mapped-in-embeddable-map-val

I am having exactly the same problem in 2019 (Hibernate 5.3.6.Final):

Fails with:

Fixed in master, 5.1, and 5.0 branches.

, thanks for your fix. II believe it will work when the column in the embeddable is annotated with:

@Column( insertable = false, updatable = false ),

but it doesn't work if the Map is annotated with:

@MapKeyColumn(name = "language", insertable = false, updatable = false)

The code checking for duplication needs to exclude non-insertable, non-updatable columns from the map key as well as the map value.

Currently, SimpleValue does not retain information about insertable or updatable columns. I plan to extend SimpleValue to do that.
