Given the class:

@PersistenceCapable
case class Employee(var department:String, var salary: Int)

and the query using Scala:
query from employee groupBy department having salary.avg > 100 select (department, salary.avg)

It generates the query:
SELECT this.department, avg(this.salary) INTO scala.Tuple2 FROM Employee GROUP BY this.department HAVING avg(this.salary) > a1

and fails to execute with the following error:
Variable a1 is unbound and cannot be determined
org.datanucleus.exceptions.NucleusUserException: Variable a1 is unbound and cannot be determined
