Support for @MappedSuperclass is lacking

[richardatsap]

If one has deep inheritance via @MappedSuperclass like

@MappedSuperclass AbstractBaseClass
- @MappedSuperclass AbstractCommentClass
- - MyEntity

the following things do not work:

• @EdmIgnore annotations in the abstract classes are not recognized (we are using @Access(AccessType.PROPERTY)) on all entities
• Properties in AbstractBaseClassare not recognized, leading to errors in generating the metadata for AbstractCommentClass and MyEntity, for navigation properties in particular, see also Fields in @MappedSuperclass are not visible #105.

I have a larger project (~100 entities) which I would like to migrate from Olingo (JPA) v2 to v4.

With the current release , only one level of MappedSuperclass is supported. This will be enhanced.

In case a MappedSuperclass is not an entity itself, it should not appear in the $metadata document, as no internal representation is created.

@access in not respected, as tuple queries are created.
