[SEC-183] - Avoid unnecessary HttpSession creation when using Anonymous and Remember-Me authentication

以前如果使用HttpSessionContextIntegrationFilter的话，不管你是否需要创建session，他都会给你创建。这在一些Base验证的时候是多余的。现在加上了forceEagerSessionCreation，在创建session的时候做了控制。

[SEC-29] - Save POST request parameters before redirect

在前几个版本出现这个问题，如果实现了登陆自动跳转，acegi仅仅是简单记录了URL，没有深入的纪录信息。新版本中acegi不仅仅是保持POST中的数据不会丢失，request里面的东西几乎全都序列化保存下来了，实现可以看看SavedRequest。

[SEC-40] - HibernateDao.scroll() performance

[SEC-92] - Hibernate ACL implementation

这个比较激动的改进在1.0的源码中没有找到，看alex的意思好像是仅仅提供各演示，目的是为了生成数据脚本方便点。（其实这个还真的没法做成特别通用的，毕竟每个人的ACL实现都有可能不同）

[SEC-147] - BasicAclEntryAfterInvocationProvider should support processDomainObjectClass

对List进行ACL交验的时候，会把第一个元素取出，看看是否AssignableFrom这个processDomainObjectClass ，算是做一下安全检查吧。

[SEC-172] - Allow SimpleAclEntry to take \'null\' as recipient constructor argument

其实应该是不允许recipient 为空。

[SEC-187] - inHttp inHttps not fully utilized in AuthenticationProcessingFilterEntryPoint

[SEC-191] - AclTag class should use the BeanFactoryUtils.beanNamesForTypeIncludingAncestors method to search for the AclManager

AclTag在寻找AclManager 时候会更加灵活了，得益于spring的强大。

明天继续吧。。。。
