Do I have to to use CollectionResponse as a return type in GAE Endpoints APIs or I can use java collections of entities?

Question

It appears that I can safely use plain java collections as return types (as long as they contain entities) in my Endpoint APIs. I was wondering if I'm missing something. Is there any benefit to using CollectionResponse instead?

Thank you.

Yes, you can safely use collections (doc here). The advantage of CollectionResponse is the built in support for paging and other nice-to-have features.
