I figured something more out by now:

Theproblem lies in the class "ServletExternalContextFake" as the stacktrace suggests. Looking in the source, the method getRequestLocales() - like many others - really is only a fake:

/**
* {@inheritDoc}
*/
public Iterator getRequestLocales() {
throw new UnsupportedOperationException();
}

" ... This class implements the nature of a servlet applicaton environment. As it's name says this class fakes the behavior described in the specifications. ... "

The problem seems to be, that if tobage is included, MyFaces JspViewHandlerImpl class calls this method per default (The external context here ist the ServletExternalContextFake class):

public Locale calculateLocale(FacesContext facesContext) {
Iterator locales = facesContext.getExternalContext().getRequestLocales();
while (locales.hasNext()) {
Locale locale = (Locale) locales.next();
for (Iterator it = facesContext.getApplication().getSupportedLocales(); it.hasNext();) {
Locale supportLocale = (Locale) it.next();
// higher priority to a language match over an exact match
// that occures further down (see Jstl Reference 1.0 8.3.1)
if (locale.getLanguage().equals(supportLocale.getLanguage()) &&
(supportLocale.getCountry() == null ||
supportLocale.getCountry().length() == 0)) {
return supportLocale;
}
else if (supportLocale.equals(locale)) {
return supportLocale;
}
}
}

Locale defaultLocale = facesContext.getApplication().getDefaultLocale();
return defaultLocale != null ? defaultLocale : Locale.getDefault();
}

Still haven't figure out a way around this...
