I upgraded to Mojarra JSF 2.2.1 (from 2.1.22) and since then for each of my requests I'm having an exception in console:

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

Request finishes succesfully when I'm not using flash scope on it. However, as I'm using this scope for FacesMessages, if I put a message here, I have a NullPointerException and the navigation flow is interrupted:

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

I also have the same problem with last version of 2.1.x branch (2.1.24). By the way, that's what my addInfoMessage method does:

/**
 * 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);
}

Being Messages class of org.omnifaces.util.Messages type.

EDITED

The problem, which happens only with firefox and when view params are involved, seems to disappear when I clear my browser's cookies. It also seems to persist in the whole 2.2.x and 2.1.x branches (at least till 2.2.4-2.1.26), displaying an slightly different trace:

com.sun.faces.context.flash.ELFlash getCurrentFlashManager GRAVE: JSF1094: Could not decode flash data from incoming cookie value Invalid characters in decrypted value. Processing will continue, but the flash is unavailable for this request.

According to @BalusC here (aug-2013):

We also encountered this in Mojarra 2.1.24. We concluded that ELFlash class is - honestly said - one terrible mess which seems to be originally written by an intern without a solid background knowledge about HTTP matters.

I don't have enough rep to comment, so I write an answer....

It happens on any browser as Stan Silvert says. 2.1.25 is fixing it, but https://java.net/jira/browse/JAVASERVERFACES-2862 is fixed on 2.1.27 for 2.1.x branch : https://java.net/jira/browse/JAVASERVERFACES-3089

2.1.27 has a due date of January 2nd, 2014.
