[jboss-jira] [JBoss JIRA] Resolved: (EJBTHREE-844) We need a optimistic locking version of TreeCacheProviderHook

We need a optimistic locking version of TreeCacheProviderHook ------------------------------------------------------------- Key: EJBTHREE-844 URL: http://jira.jboss.com/jira/browse/EJBTHREE-844 Project: EJB 3.0 Issue Type: Bug Components: Clustering Affects Versions: EJB 3.0 RC9 - Patch 1, EJB 3.0 RC9 - FD Reporter: Galder Zamarreno Assigned To: Brian Stansberry Fix For: AS 4.2.0 CR1 Attachments: OptimisticTreeCacheProviderHook.java Original Estimate: 4 hours Remaining Estimate: 4 hours Currently, EJB3/Hibernate cannot take advantage of using a second level cache based in optimistic locking in a EJB3 environment. We only have a TreeCacheProviderHook CacheProvider for pessimistic locking which means that if a customer wants to set up optimistic locking, it's forced to use OptimisticTreeCacheProvider. However, this class was not designed for managed environments and ends up creating another cache, so you end up with two caches for the same job in the same instance which is wrong. I have created a OptimisticTreeCacheProviderHook which creates an org.hibernate.cache.OptimisticTreeCache based on the TreeCacheMBean instance looked up. Please find attached. This could be improved by creating a accessor method for TreeCacheProviderHook.cache, so that I can directly extend it rather than reimplementing CacheProvider. But, I have followed the CacheProvider implementation path so that I can quickly send a patched jar to the customer containing just this class.
