-----------------------------------------------------------------
I first wrote a changeset_2510.diff patch which works locally and on cluster
but does not take into account the Manager type. I think it's ok but to be sure
I have also created a patch with no possible regression: OFBIZ-4289_Login out
on a cluster handled by DeltaManager causes a NPE.patch
So changeset_2510.diff is not intended for inclusion. But I'm curious to know
why it works. Tough I have no time to digg in further on why we need to put
delegator, dispatcher, security and authorization in session. So if someone is
interested...

> It works locally but not on clusters. You simply get a NPE.
> h3. Problem
> * When we logout we cross an issue due to Tomcat sessions persistence.
> * Because we set distributable to true, to allow sessions failover,
> * and use and DeltaManager for replication.
> * Delegator and other main Classes (notably Dispatcher) are not
> serialized in OFBiz. This is the origin of the problem
> h3. Tried solutions
> By default DeltaManager save active sessions on disk. It uses a private
> String variable pathname for that (default to "SESSIONS.ser"). You can set it
> to null, to avoid session persistence, using a context.xml file in the
> WEB-INF folder with content like below. But I tried it in webtools app on
> staging qs001 (only) and it did not work (with distributable set to false).
> And we have no other means to set it from OFBiz (OOTB).
