The following query
{code}
public void testSumOrderBy() {
    QueryFactory qf = getQueryFactory();
    Query q = qf.from(getModelFactory().getUserImplClass())
            .select(Expression.sum("age"))
            .orderBy(Expression.sum("age"))
            .build();
}
{code}

in the context of QueryDslConditionsTest test class fails with
