Projection fails with InstantiationException after Hibernate 6 migration

Hibernate ORM
1

After the migration to Quarkus 3.14 and Hibernate 6, custom query projections stopped working.

I have many more examples but all comes to this exception and combination of a custom query and an aggregate class projection.

The exception I get:

org.hibernate.InstantiationException: Cannot instantiate query result type  'xx.domain.UnitDetails' due to: xx.domain.BusinessUnitDetails.<init>(java.lang.String,xx.domain.BusinessUnitType,java.lang.Integer)

Repository layer, script:

fun getSender(senderId: Long): UnitDetails {
    return find(
        "SELECT ud.code, ud.type, route.sequence " +
            "FROM RouteEntity route " +
            "JOIN UnitDetailsEntity ud ON ud.id = route.senderUnitDetailsId "
    ).project(UnitDetails::class.java).list()
}

The aggregate class I use to project with a custom constructor to satisfy hibernate:

class UnitDetails(
    val businessUnit: BusinessUnit,
    val sequence: Int
) {
    constructor(
        code: String,
        type: BusinessUnitType,
        sequence: Int
    ) : this(BusinessUnit(code, type), sequence)
}
