ParameterizedTypeReference<CollectionModel<EntityModel<>>> returns empty content from RestTemplate / WebClient

I'm trying to retrieve CollectionModel<EntityModel> content from an http response body (I've tried TestRestTemplate and WebClient and both produce same results) but getting an empty content in the CollectionModel: CollectionModel { content: [], fallbackType: null, links: [] }

I can see that the response body actually has data because when I change the type to be returned as string instead of using ParameterizedTypeReference, then the response body is a valid json string like :

{
  "_embedded": {
    "entities": [...]
  },
  "_links": {...}
}

In the debug logs, the Writing part of the body also shows correct results:

[io-64000-exec-1] m.m.a.RequestResponseBodyMethodProcessor : Writing [CollectionModel { content: [EntityModel { content: MyEntity(id=1, name=Test, (truncated)...]

So the issue seems to be in the reading mapping.

Is any special configuration required for this to work?
I've searched around and couldn't find anything on how to make it work.

At the same time, ParameterizedTypeReference<EntityModel<MyEntity>> works as expected. So there's something wrong with mapping the ParameterizedTypeReference<CollectionModel<>> in particular.
