Intermittente java.lang.IndexOutOfBoundsException su javax.faces.component.AttachedObjectListHolder.restoreState

Question

Possiedo un'applicazione JSF 2.1.21 con metodo di salvataggio stato client. Sto anche usando PrimeFaces 3.5 + Tomcat 7.0.37.

Uso il gestore di eccezioni ajax completo OmniFaces per visualizzare una pagina di errore personalizzata e inviarmi un'e-mail con lo stacktrace quando si verifica un problema.

Ogni giorno ricevo almeno un'email con java.lang.IndexOutOfBoundsException. Sembra essere correlato alla ridistribuzione dell'applicazione, ma non sono in grado di riprodurlo.

Ecco la stacktrace:

StackOverflow alla fine mi ricorda questa domanda esistenza, così mi prendo qualche minuto per rispondere come ho risolto.

Suppongo che non sia possibile sostituire una webapp JSF in esecuzione senza eccezioni relative allo stato di visualizzazione se la struttura della pagina a cui l'utente stava accedendo è stata modificata in qualche modo.

Sono stato in grado di risolvere perfettamente questo utilizzando la distribuzione parallela di Tomcat, in cui le versioni precedenti della webapp rimangono sul server fino a quando non hanno sessioni attive.
