Described by Nicolas Filotto: "A risk of getting inconsistencies in the cache if we met issues with the DB (DB Deadlock or a constraint violation). I had to duplicate several classes of ISPN to fix the bug locally by applying the same logic as the one we had in JBC. This issue is obviously due to a workaround used by the ISPN team to avoid issues with distributed caches so I guess they won't accept to provide any fix for this one.

Needed by JBoss Portal
Patching this is a significant change and cannot be done in a minor. As per the forum[1], Nicolas fixed the problem through by extending the cache store. [1] https://community.jboss.org/message/843826
