Robert Becker commented on JBSEAM-5143:
---------------------------------------

Sadly, there are still "Stack must not be null" exceptions being logged by JBoss. As I am out of the office for the next couple of days I can not investigate this further for now. I will try some more debugging when I am back.

Also, I just noticed this in logs: https://developer.jboss.org/thread/229275?tstart=0

>          Issue Type: Bug

> Since upgrading to Seam 2.3 with Mojarra 2.1.29 on glassfish v3 from Seam 2.2.2, I get random IllegalArgumentExceptions with the message "Stack must not be null". The application worked fine for several years until now.
> The full stack trace is listed here: http://pastebin.com/RjLndvnE
> The exception randomly happens (in about 1 of 500 requests) when navigating between pages, submitting forms, switching (RichFaces) tabs and so on.
> I believe restarting glassfish and/or enabling client side state saving reduces the frequency of the issue whereas it seems to happen more often after multiple successive redeployments during development.  Sadly, due to several dependencies this is already in production but happens far less often there, but it still happens daily according to the server logs.
> I have also posted this on stackoverflow (http://stackoverflow.com/questions/27107870/seam-2-3-illegalargumentexception-stack-must-not-be-null) but have not received any answers yet.
> Besides Seam 2.3, the following libraries are used:
> - Mojarra 2.1.29
> - RF 4.5 (exception also occurred with 4.3.x)
> - Omnifaces 1.10RC1 (will upgrade to 2.0)
> - Primefaces 5.1
