Description
When you have a Resources collection as a property inside a class which extends ResourceSupport which also contains its own namespaced links the curie _links are serialised twice:
I believe this is because both the parent resource and the Resources property are treated as being at root level by the serializer and so the curie creation is doubled up.

Research direction
No files or tests are named. Start by locating the serializer handling ResourceSupport and Resources collections, then reproduce the JSON shape in the issue with a namespaced parent and embedded collection. Done means the representation contains one _links object and one curies entry rather than serializing the curies twice.
