[infinispan-dev] SingletonStoreTest in trunk

[Galder Zamarreno]

JGroups seems to be dropping the message directed to a node that is up 
and this leads to a replication timeout.

The test starts 3 cache instances:

2009-06-04 11:36:38,771 4278  INFO 
[org.infinispan.remoting.transport.jgroups.JGroupsTransport] (main:) 
Received new cluster view: [localhost.localdomain-23373|2] 
[localhost.localdomain-23373, localhost.localdomain-4344, 
localhost.localdomain-15374]

Then adds some data to one of the, cache[0] 
(localhost.localdomain-23373), and stops it. This is the new view installed:

2009-06-04 11:36:39,047 4554  INFO 
[org.infinispan.remoting.transport.jgroups.JGroupsTransport] 
(Incoming-2,Infinispan-Cluster,localhost.localdomain-15374:) Received 
new cluster view: [localhost.localdomain-4344|3] 
[localhost.localdomain-4344, localhost.localdomain-15374]

The test now takes cache[1] and adds some data there but JGroups is 
dropping data that needs to be replicated to cache[2] as shown by these 
WARN messages:

2009-06-04 11:36:44,765 10272 WARN  [org.jgroups.protocols.TCP] 
(Timer-2,Infinispan-Cluster,localhost.localdomain-4344:) no physical 
address for localhost.localdomain-15374, dropping message
2009-06-04 11:36:50,766 16273 WARN  [org.jgroups.protocols.TCP] 
(Timer-1,Infinispan-Cluster,localhost.localdomain-4344:) no physical 
address for localhost.localdomain-15374, dropping message

I don't know why JGroups is doing this but enabling TRACE on org.jgroups 
should clarify it. Vladimir, can you look to why JGroups throws these 
WARN messages? localhost.localdomain-15374 is still up and running, it's 
localhost.localdomain-23373 that was stopped. Looks like JGroups might 
be confusing both?
