Cache invalidation in OptimisticTreeCache conflicts with JTA transactions
-------------------------------------------------------------------------

         Key: HHH-1764
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1764
     Project: Hibernate3
        Type: Patch

  Components: core  
    Versions: 3.2.0.cr2    
 Environment: Hibernate 3.1.3 with added OptimisticTreeCache classes from 3.2.0.cr2, JBoss Cache 1.3 SP2, JBoss 4.0.3 SP1, PostgreSQL 8.1.2
    Reporter: Jaka Jaksic
 Attachments: OptimisticTreeCache.patch

After switching to Hibernate 3.2.0.cr2's OptimisticTreeCache, exceptions started to occur after every commit. The reason is that, unlike TreeCache, OptimisticTreeCache doesn't perform cache invalidation _outside_ the scope of JTA transaction, even though the comment in its put() method states so... So because cache invalidation happens after commit, when the tx status is set to 3 (STATUS_COMMITTED), which TreeCache finds invalid, the following exception occurs:

00:53:51,754 WARN  [TreeCache] status is 3 (not ACTIVE or PREPARING); returning null)
00:53:51,754 INFO  [TxInterceptor] There was a problem handling this request org.jboss.cache.CacheException: Must be in a valid transaction _put(null, /org/hibernate/cache/UpdateTimestampsCache/EVENT_LOG, item, 11479064317, true)

The original TreeCache properly bypasses JTA transaction by calling suspend(). I don't know why OptimisticTreeCache doesn't do that as well. I just copied that code from the TreeCache class and it seems to work well.

If there is a reason why OptimisticTreeCache should not do it this way, please let me know what it is and how to solve this problem properly. Otherwise just use the provided patch.


Here's the full stack trace:
