I know that it's an old question, but you can create an object to store info

public class UserCount {
   private String username;
   private Long count;

   public UserCount(String user, Long count){
      this.username = user;
      this.count = count;
   }

}

It's important to create the constructor and to pass the parameters in the correct way.

The JPQL became

select my.package.UserCount(i.username, count(i.uuid) ) from schema.information i where i.entereddt between :start and :end group by i.username

The query returns a List .
