[jboss-user] [JBoss Cache: Core Edition] - Problem with SERIALIZABLE Isolation Level

[andre.rigon]

Hello guys,

I'm using JBossCache 1.4.1.SP9.
I need to use SERIALIZABLE isolation level in my application.
I did the following test:

1) started one jboss instance and at some point did:


  | TreeCache cache = cacheManagerImpl.getCache();
  | cache.put("1", "1", "test");
  | cache.getTransactionManager().begin();
  | cache.put("1", "1", "test2");
  | 
and never call commit.

in other jboss instance, I did:


  | TreeCache cache = cacheManagerImpl.getCache();
  | cache.getTransactionManager().begin();
  | @SuppressWarnings("unchecked")
  | T returnString = (T) cache.get("1", "1");
  | cache.getTransactionManager().commit();
  | return returnString;
  | 

So, I was expecting a failure, because the isolation level is SERIALIZABLE, and I didnt make a commit in the first jboss instance.

But the second code block succeed with no error.
If a had inserted a cache.put(..)  in the second block, it would fail.

Are my expects corrects? Or I misunderstanding something? 

thanks in advance,

andre
