Document that UserType implementations may need to be Serializable
------------------------------------------------------------------

                 Key: HHH-3380
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3380
             Project: Hibernate3
          Issue Type: Improvement
          Components: core
         Environment: ehcache 1.5.0b2
            Reporter: Manuel Dominguez Sarmiento
            Priority: Trivial


We found out that Hibernate UserTypes need to be Serializable in order for query caches to be serializable. This is not documented.

Strictly speaking, if the cache implementation does not require object graphs to be serializable, this is not a problem, so I'm not sure whether UserType should extend Serializable. However, given that many cache implementations require this either for distributed caching or disk persistence (as is our case), it may be wise to do this, or at least document it.
