I have JBoss Cache 2 setup as my second level cache in a two node cluster. I see that
changes from one node are replicated to the other node OK but they are not being persisted
into the actual database, they seem to be sitting in the second level cache. I checked the
org.jboss.cache.DataContainerImpl MBean and saw that the replicated object is there.
Why isn't the replicated object being persisted to the database?
