                 Key: JBCACHE-1287
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-1287
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Cache loaders
    Affects Versions: 2.1.0.CR3
            Reporter: Brian Stansberry
         Assigned To: Manik Surtani
            Priority: Critical


Cache loaders no longer are able to deserialize types not visible to the cache's classloader during load operations.

New test org.jboss.test.marshall.CacheLoaderMarshallingTest shows the issue.

When trying to deserialize, the cache loaders are calling into the marshalling code.  The marshalling code *always* sets the TCCL to the cache's class loader. So, if a caller app properly sets its TCCL to one that can load the app's custom types, tje marshalling code will undo this.

If region-based marshalling is enabled, the correct classloader still isn't assigned, because the serialized data does not include the FQN information needed to find the correct region.  So again the cache's class loader is used.

This is all a side effect of using the replication marshalling code for cache loader ops, which are somewhat different use cases.  When deserializing a replication message, the JGroups thread is unlikely to  have a TCCL that has visibility to the needed types.  Cache loader load operations usually have the correct TCCL in place.
