Problem with Multiplexer and state transfer
-------------------------------------------

                 Key: JGRP-280
                 URL: http://jira.jboss.com/jira/browse/JGRP-280
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.3 SP1, 2.3
            Reporter: Bela Ban
         Assigned To: Bela Ban
             Fix For: 2.4


Was looking at server logs from a testsuite run when I noticed something
odd.

We've got a 2 node cluster, node0 and node1, running the "all" config.
Sequence of events:

1) node0 starts; as part of normal start of an "all" config 5 different
services deploy sharing a channel (4 JBC instances + ClusterPartition)
2) Then node1 starts, and deploys the same 5 services.  All is fine,
incl state transfers from node0.

3) Test driver copies to node0/deploy a sar with 3 more services that
use the same channel as the previous 5.  This goes fine on node0, but on
node1 I find a bunch of ERROR and WARN messages in the log (see below).
4) Test driver copies sar to node1/deploy.  The 3 services deploy on
node1 without problem; no further error messages. 
5) The test itself passes fine; I just happened to see the following in
the logs.

Following are the messages.  Looks like 1) node1 gets a state transfer
request for the BadPartition-TreeCache service, which AFAICT it
shouldn't. 2) The Multiplexer throws an exception on the request instead
of logging a WARN, and 3) when the Multiplexer gets a view for a service
it doesn't have, it logs a WARN, which should probably be an INFO, as
its not a sign of something wrong in this case.
