Research direction
Start by examining RepositoryRestController.entity and RepositoryRestController.linkedEntity, the locations named in the report. Reproduce the wrong-id-type error with an entity extending AbstractPersistable and inspect how the inherited identifier is handled. Done means mapped-superclass entities no longer produce the reported Long-versus-String error.
