        PersistenceContext persistenceContext = sessionImpl.getPersistenceContext();
        Field entityEntriesField = StatefulPersistenceContext.class.getDeclaredField("entityEntries");
        entityEntriesField.setAccessible(true);
        IdentityMap map = (IdentityMap) entityEntriesField.get(persistenceContext);
        log.info(map);
    } catch (Exception e)
    {
        log.error(e);
    }

}
