Using lazy deserialization with application specific cache keys, remote handling of a cache invalidation operation triggers MarshalledValue.equals(...) on the cache key, triggering deserialization and causes a ClassNotFoundException in my environment, due to the class not being found in the context classloader of the jgroups receiver thread.

The user of the cache in this case is the 2nd level cache of an entity manager via the hibernate-infinispan cache provider. While the cache is specific to the application, the cache manager is not, and is managed via the AS, which probably accounts for the classloader issue.
