Not sure about the first problem, but for the second one, try returning a
non-parameterized type, e.g.,
public class PlayerList extends List<Player> {
// ... whatever constructor you need
}
and then change the @Get signature to
@Get public PlayerList retrieve() ...
The problem, I think, is that List<Player>, under type erasure, looks like a
raw List, and the deserialization machinery doesn't know what to do with
that. PlayerList, however, can be deserialized because it has the knowledge
that its elements are Players embedded within it.
