      JBoss Cache unmarshalled return values that were going to be discarded during replication. When the cache contained objects in an isolated classloader, it was unable to unmarshall the objects and an exception was thrown, preventing the replication from succeeding. The return values are now no longer unmarshalled since they will be discarded. The exception is therefore not thrown and the replication finishes successfully.

      Description

      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.
