删除实体时的Stackoverflow

Question

我正在使用Eclipse链接，我想删除所有带有子句的实体。但是当我这样做时，我得到了StackOverFlow错误。这是我用于删除的方法。有什么问题？

EntityManager em = getEntityManager();
       try {
             ACLEntry acle =  new ACLEntry();
            TypedQuery<ACLEntry> q = em.createQuery("DELETE  from ACLEntry acle  where        acle.acl=:acl ", ACLEntry.class);
            q.setParameter("acl", acl);

           } catch (Exception ex) {
            LOG.throwing("DAO", "removeAllACLEntries", ex);
        // em.getTransaction().rollback();
        }
          finally {
            em.close();
       }
           }   

这是ACLEnrty实体：
