------------------------------------

             Summary: ClassNotFoundException during replication with lazy deserialization
                 Key: JBCACHE-1617
                 URL: https://issues.jboss.org/browse/JBCACHE-1617
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Replication
    Affects Versions: 3.2.8.GA
            Reporter: Dennis Reed
            Assignee: Dennis Reed


Replicating a cache put tries to deserialize the original value on the remote nodes.
If the classloader of the JGroups call is not the correct classloader for the value, a ClassCastException occurs and aborts the put.
Since the value is never returned, it should not be deserialized.
