createNativeQuery(queryString,Tuple.class).getResultList() method is not returning list of Tuple data

I am using reactive hibernate (1.0.0.CR7) for my spring webflux project. I am getting the object array data while executing native queries and it is working fine. But I need it as a tuple object. So I passed Tuple.class as a second argument to createNativeQuery method. But it will throw an exception as it cannot cast an object to tuple. I just need the data with column alias name. So I choose tuple instead of object array. Kindly help.

Sample code :

String queryString= "select c.country_name as country_name, c.phone_code as phone_code
from erp_country c"; // MySql query
Mutiny.Query<Tuple> query = session.createNativeQuery(queryString, Tuple.class);
List<Tuple> list = query.getResultList().await().indefinitely();
for (Tuple tuple : list) { // here it will throw an exception as object cannot be cast to class javax.persistence.Tuple
     System.out.println(tuple.get("country_name") + "-" + tuple.get("phone_code"));
}

Exception Message:

Ljava.lang.Object; cannot be cast to class javax.persistence.Tuple ([Ljava.lang.Object; is in module java.base of loader 'bootstrap'; javax.persistence.Tuple is in unnamed module of loader 'app')

I have another project using JPA- hibernate 5.5. There I can pass the second parameter of createNativeQuery as tuple class instead of giving an entity class. So I thought may be there is a chance to use Tuple in reactive hibernate also. If we use tuple class then we can retrieve the data by using alias name in the query string.

Hah. I did not know (or once knew and forgot) that this world in plain Hibernate.

I had the same exact reaction 😃

Thanks @nivinps

Hah. I did not know (or once knew and forgot) that this worked in plain Hibernate.

But if it does, then it should be pretty easy to make it work in HR.
