> The following test case executes query two times. 
> The sql generated for the first time:
> sql = SELECT t0.KEYNAME, t0.KEYVAL FROM KEYGEN t0 WHERE (t0.KEYNAME = ?)  optimize for 1 row FOR READ ONLY WITH RR USE AND KEEP UPDATE LOCKS
> The sql generated for the second time:
> sql = SELECT t0.KEYNAME, t0.KEYVAL FROM KEYGEN t0 WHERE (t0.KEYNAME = ?)
>    public void testKeyGen() {
>         EntityManager em = emf.createEntityManager();
>         KeyGenEntity key = null;
>         em.getTransaction().begin();
