Entity Remains in L2 Cache After StaleObjectStateException
----------------------------------------------------------

                 Key: HHH-5678
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5678
             Project: Hibernate Core
          Issue Type: Bug
          Components: caching (L2), core
    Affects Versions: 3.5.6
         Environment: Hibernate 3.5.6, problem has been reproduced on multiple databases (MySQL 5.1, Oracle 11g, SQL Server 2005, SQL Server 2008)
            Reporter: j nadler
            Priority: Critical


StaleObjectStateExceptions will happen, and the optimistic locking mechanism is a great benefit overall for our application.   Unfortunately after this occurs, the invalid (version mismatch with DB) version of the entity can get 'stuck' in the L2 cache.   

We could write application level code to handle this, but it's ugly and intrusive.   The best solution is for Hibernate Core to evict from L2 whenever a StaleObjectStateException is thrown.

If you didn't want to change current behavior this could be configurable I guess.   The default behavior should probably be 'evict'.
