关于Mojarra JSF中闪存的例外情况

Question

我升级到Mojarra JSF 2.2.1(从2.1.22开始),从那时起我的每个请求都在控制台中出现异常:

GRAVE: JSF1094: Could not decode flash data from incoming cookie value /?.  
Processing will continue, but the flash is unavailable for this request.
com.sun.faces.lifecycle.InvokeApplicationPhase execute

当我没有使用闪存范围时,请求成功完成.但是,因为我正在使用此范围FacesMessages,如果我在此处输入消息,我有一个NullPointerException并且导航流程被中断:

GRAVE: El Servlet.service() para servlet Faces Servlet lanzó una excepción
java.lang.NullPointerException

我对2.1.x分支的最新版本(2.1.24)也有同样的问题.顺便说一下,这就是我的addInfoMessage方法所做的:

/**
 * Add information message.
 * 
 * @param msg
 *            the information message
 */
public void addInfoMessage(String msg) {
    addInfoMessage(null, msg);
}

/**
 * Add information message to a specific client.
 * 
 * @param clientId
 *            the client id
 * @param msg
 *            the information message
 */
public void addInfoMessage(String clientId, String msg) {
    Messages.addFlashInfo(clientId, msg);
}

作为Messages类的org.omnifaces.util.Messages类型.

EDITED

当我清除浏览器的cookie时,只有firefox和涉及视图参数时出现的问题似乎消失了.它似乎仍然存在于整个2.2.x和2.1.x分支中(至少直到2.2.4-2.1.26),显示略有不同的跟踪:

com.sun.faces.context.flash.ELFlash getCurrentFlashManager GRAVE:JSF1094:无法解码来自传入cookie值的闪存数据解密值中的无效字符.处理将继续,但闪存不可用于此请求.

根据@BalusC 在这里(aug-2013):

我们在Mojarra 2.1.24中也遇到过这种情况.我们得出结论,ELFlash类是 - 老实说 - 一个可怕的混乱,似乎最初是由一个实习生写的,没有关于HTTP问题的扎实的背景知识.

我可以在任何浏览器上重现该问题。我刚刚打开https://java.net/jira/browse/JAVASERVERFACES-2973来解决这个问题。
