JPA Mapping limitations
There are 3 known JPA mappings that Ebean does not support.
Only single table inheritance is supported.
There is no planned support for JOINED or TABLE PER CLASS inheritance strategies.
Only a single type converter per type is supported.
JPA @Converter autoApply false is not honoured. This means that we expect a type to be mapped consistently for all properties that it is used. For example, we can't have to Converters mapping Boolean two different ways in the same Ebean database instance.
@Embeddable class does not support @OneToMany / @ElementCollection.
As @Embeddable does not have identity the case of supporting collections gets ugly. At this stage there is no planned support for this.
