              If the window is being disposed, any Exceptions that occur must simply be discarded: no useful action can be taken.

              The root cause is the need to run a JSF lifecycle to dispose @WindowDisposed View Scoped beans. When the session is expired, the lifecycle execution fails, but the beans have already been garbage collected at this time.
