java.lang.IllegalStateException -响应提交后无法创建会话

我在我的项目中使用JSF + PrimeFaces。我为此准备了一个Maven项目。当我编译我的项目时，当主页加载后，我得到了以下异常：

这是Mojarra中的一个bug，据报道与其他issue 2277一样。在Mojarra 2.1.8中已经修复了这个问题。Currently mojarra2.1.9已经可用。只要升级到最新版本，这个问题就会消失。
原因是在第一个请求中创建会话太晚，该请求返回一个相对较大的页面，其中视图或会话范围的托管bean在页面中相对较晚首次被引用。视图或会话范围的bean需要存储在会话中。如果会话还不存在，则需要创建它。
当第一次创建会话时，服务器需要在响应头中设置needs。但是只有在响应还没有发送(提交)给客户端的情况下，这才是可能的。当这种情况已经发生时，您将面临这种异常。响应缓冲区溢出时，响应的一部分可能已经自动发送，这取决于服务器配置，通常是2KB。您的页面明显大于该缓冲区大小。
