Keycloack does not detect #SqlResultSetMapping in custom provider jar - keycloak

Question

I am trying to create a custom query in Keycloak in my custom provider Jar. The annotation below is not detected. I had to resort to use the call that returns a list of objects from which I can extract the columns from the result set. However I would like to use the SqlResultSetMapping interface. Here is the code that I am using.
#MappedSuperclass
#SqlResultSetMapping( name = "GroupTabularDataMapping",
classes = {
#ConstructorResult(
targetClass = GroupTabularData.class,
columns = {
#ColumnResult(name = "id"),
#ColumnResult(name = "name"),
#ColumnResult(name = "updated_by"),
#ColumnResult(name = "updated_by_email"),
#ColumnResult(name = "last_updated"),
#ColumnResult(name = "count",type = Long.class)
})
})
public class GroupTabularData {
private String id;
private String name;
private String updatedBy;
private String updatedByEmail;
private String lastUpdated;
private BigInteger count;
public GroupTabularData(String id, String name, String updatedBy, String updatedByEmail,
String lastUpdated, BigInteger count) {
this.id = id;
this.name = name;
this.updatedBy = updatedBy;
this.updatedByEmail = updatedByEmail;
this.lastUpdated = lastUpdated;
this.count = count;
}
public GroupTabularData(Object objArr) {
Object[] arr = (Object[]) objArr;
this.id = arr[0].toString();
this.name = arr[1].toString();
this.updatedBy = arr[2].toString();
this.updatedByEmail = arr[3].toString();
this.lastUpdated = arr[4].toString();
this.count = (BigInteger)arr[5];
}
}
This call works:
Object resultData = q.getResultList().stream().map(
objArr -> new GroupTabularData(objArr)).collect(Collectors.toList());
But this one does not:
Query q = em.createNativeQuery(GROUP_TABULAR_QUERY, "GroupTabularDataMapping");
List<GroupTabularData> resultData = q.getResultList();
I imagine that the reason is because I need to add my class to the scanning list of JPA but I don't know which file I need to update or if it is some other configuration. I appreciate any leads.
