PojoCache will rollback concurrent transaction using optimistic locking
-----------------------------------------------------------------------

                 Key: JBCACHE-915
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-915
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: PojoCache
            Reporter: Ben Wang
         Assigned To: Ben Wang
             Fix For: 2.0.0.GA


This is reported in the forum. Concurrent tx on any pojocache pojo will cause rollback under ALPHA1 release. This is clearly a drawback in the combination of PojoCache and optimistic locking becuase we create a new node under "_JBOSS_INTERNAL__" each time a pojo is created.

Partial get around is to use Cache.getRegion() api as in this code snippet:
      String configFile = "META-INF/local-service.xml";
      boolean toStart = false;
      cache_ = PojoCacheFactory.createCache(configFile, toStart);
      cache_.start();
      cache_.getCache().getRegion(Fqn.fromString(REGION), true);

This will trigger a region creation and subsquent pojocache operation under that region will be placed separately.
