Fetching QueryResults from a query having both groupBy and having clause results in a QuerySyntaxException

[uvpoblotzki]

Fetching QueryResults from a query having both groupBy and having clause results in a QuerySyntaxException. Here are two test cases, the first one executes without error the second results in the above described error:

    @Test
    public void groupByHavingFetch() {
        QCustomer customer = QCustomer.customer;
        JPAQuery<Customer> customerQuery = new JPAQuery<Customer>(entityManager, HQLTemplates.DEFAULT).from(customer);

        customerQuery.groupBy(customer.lastName).having(customer.id.count().gt(1)).fetch();
    }

    @Test
    public void groupByHavingFetchResults() {
        QCustomer customer = QCustomer.customer;
        JPAQuery<Customer> customerQuery = new JPAQuery<Customer>(entityManager, HQLTemplates.DEFAULT).from(customer);

        customerQuery.groupBy(customer.lastName).having(customer.id.count().gt(1)).fetchResults();
    }

The test in error generates following error:

java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: having near line 3, column 1 [select count(distinct customer.lastName)
from Customer customer
having count(customer.id) > ?1]

The resulting hql Statement is missing the groupBy clause.
