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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
