If user handles successfully handles ViewExpiredExpception with
http://weblogs.java.net/blog/edburns/archive/2009/09/03/dealing-gracefully-viewexpiredexception-jsf2,
myfaces still produce following output in log:

The stacktrace comes from StateUtils.reconstruct(String, ExternalContext):
if (log.isLoggable(Level.SEVERE))
{
log.log(Level.SEVERE, "View State cannot be reconstructed", e);
}
This SEVERE log is unnecessary, because real ViewExpiredExpcetion is thrown
from RestoreViewExecutor.
