This is not intermittent for me - it happens every time.
I am mixing JBoss RichFaces and Tomahawk together. If you follow the advice
given on the RichFaces page...
http://www.jboss.org/file-access/default/members/jbossrichfaces/freezone/docs/devguide/en/html_single/index.html#ApacheMyFaces
...which says "the RichFaces filter must be the first one among other filters",
then the RichFaces filter gets hit first. It tries to get a FacesContext, which
in turn triggers TomahawkFacesContextFactory.getFacesContext, and because the
Tomahawk extensions filter hasn't been hit yet you get this error.
It would be okay if it was a warning, but as Tomahawk fails so hard it halts
the entire filter chain.
See below. RichFaces (org.ajax4jsf.webapp.BaseFilter.doFilter) triggers
Tomahawk
(org.apache.myfaces.webapp.filter.TomahawkFacesContextFactory.getFacesContext)
prematurely.

Sorry, I have that wrong.
The cause is not the <security-constraint>. The cause is I am mixing JBoss
RichFaces and Tomahawk together. If you follow the advice given on the

> Resource mapping missing / throwExtensionsFilterMissing reported incorrectly
> under load
> ---------------------------------------------------------------------------------------
>
> Key: TOMAHAWK-1170
> URL: https://issues.apache.org/jira/browse/TOMAHAWK-1170
> Project: MyFaces Tomahawk
> Issue Type: Bug
> Components: ExtensionsFilter
> Affects Versions: 1.1.7-SNAPSHOT
> Reporter: Simon Kitching
>
> It has been reported by two users that under load an application using
> Tomahawk intermittently throws an exception claiming "resource mapping
> missing".
> This message is meant to be thrown when a component in a request wants to
> register stuff for the extensions filter to output, but the current request
> never passed through the extensions filter. This is a sanity check to ensure
> that people that misconfigure the ExtensionsFilter get a helpful error
> message rather than just having tomahawk components that need additional
> resources acting weirdly.
> A workaround is to disable this safety check. The first reporter of this
> problem did disable the check and found the issue disappeared.
> The problem appears to be a race condition between multiple threads *reading*
> a map; at least that was the only piece of code I found that had any obvious
> thread race issues. I can't remember the exact piece of code for the moment,
> but will update this issue when I find it again.
