hi all, i am testing JBossCache (version 1.4.1.SP3) Transaction Isolation levels. For this reason i have developed a simple test application that creates 2 threads that concurrently perform local transactions. All the examples have been done with Postgres-8.2.1, and everytime i have changed JBossCache Transaction Isolation level, i have changed the corresponding one in the database. Thread 1: looks for a bean with primary key 1 and prints it, then sleeps for 2 seconds. when it wakes up, looks again for bean with primary key 1 and prints it. Thread 2: creates and persist a bean with primary key 1. Everytime Thread 1 starts its execution before Thread 2. | @TransactionAttribute(TransactionAttributeType.REQUIRED) | public void doTransaction(int id) throws Exception { | System.out.println(id + ": start transaction"); | | // Thread 2 | if((id % 2) == 0) { | em.persist(new Tx(1, 0, "adapt19")); | System.out.println(id + ": inserted 1"); | } | // Thread 1 | else { | Tx tx = em.find(Tx.class, 1); | System.out.println(id + ": " + tx); | Thread.currentThread().sleep(2000); | tx = em.find(Tx.class, 1); | System.out.println(id + ": " + tx); | } | | System.out.println(id + ": end transaction"); | } catch(Exception e) {e.printStackTrace();} | Serializable: ok Repeatable read: no | 1: start tx | 2: start tx | 1: null | 2: inserted 1 | 2: end tx | 1: 1, 0, adapt19 [should be null] | 1: end tx | Read committed: ok Read uncommitted: no (When trying to test this Isolation level i have inserted a delay in Thread 2 to make it commit after Thraed 1) | 1: start tx | 1: null | 2: start tx | 2: inserted 1 | 1: null [shuold be 1, 0, adapt19] | 1: end tx | 2: end tx | Now my question is: is there something wrong with JBossCache Transaction Isolation levels, or something wrong with my test application?
