Will rethrow an exception that happened on root context startup, to differentiate between a failed context startup and no context at all.
Returns the session mutex attribute if available; usually,
this means that the HttpSessionMutexListener needs to be defined
in web.xml. Falls back to the Session reference itself
if no mutex attribute found.
The session mutex is guaranteed to be the same object during
the entire lifetime of the session, available under the key defined
by the SESSION_MUTEX_ATTRIBUTE constant. It serves as a
safe reference to synchronize on for locking on the current session.
In many cases, the Session reference itself is a safe mutex as well, since it will always be the same object reference for the same active logical session. However, this is not guaranteed across different servlet containers; the only 100% safe way is a session mutex.
Will rethrow an exception that happened on root context startup, to differentiate between a failed context startup and no context at all.
