org.apache.openjpa.kernel.OpenJPAStateManager.fetch()
Return the externalized value of the field with the given index as an object. If there is no externalizer, this is equivalent to {@link #fetchField}.

        OpenJPAStateManager sm = broker.getStateManager(basic);
        assertNotNull(sm);
        assertEquals(sm.getManagedInstance(), basic);


        FieldMetaData fmd = sm.getMetaData().getField("stringField");
        assertEquals("foo", sm.fetch(fmd.getIndex()));
        assertTrue(sm.getLoaded().get(fmd.getIndex()));


        pm.evict(basic);
        assertFalse(sm.getLoaded().get(fmd.getIndex()));
        // lazy loading
