We have ehcache-jgroupsreplicator 1.7, ehcache 2.6, hibernate-ehcache 4.1.5SP1, jgroups 3.1.0. When we add two initial hosts to jgroups for the ehcache cluster, our cache starts throwing these warnings at bootup:

Code:
2012-08-06 15:30:19,755 WARN  [Incoming-1,Ehcache_Channel,MarkMac-37554] jgroups.JGroupsBootstrapManager - No BootstrapRequest registered for cache com.test.model.code.TestCode,

And these errors when saving entities:

         ... 18 more


However, the second level cache appears to be working. I see hits and I see puts.

I can post the configs, but maybe these messages mean something to someone?

I wound up doing two things which seems to have resolved it:

1) updated the jgroups tcp configuration for that cache. jgroups 3.x has some significant changes to their api. So, I grabbed tcp.xml from the jar and modified just the bind port and initial hosts strings. This seemed to clear up the bootstrap warnings.

Note: the example tcp unicast configs here: http://ehcache.org/documentation/replication/jgroups-replicated-caching won't work with jgroups3.

2) to deal with the sessionfactory deserialization messages, I needed to just define the hibernate. session_factory_name which sets up a jndi context and this gets rid of these messages. (which again, didn't seem to be causing a problem anyway)

I figured the latter out thanks to this fine blog post:
