[infinispan-dev] stale persisted data?

Changing the topic as I have more info, and found that the problem is elsewhere. First -- ClassResolver used does use SML, not not plain ML. Stack trace was somehow misleading. So, we're fine there, no false config used. But, this is what I could find now. This is my test (see below) - JPA over JDO over DataNucleus over GAE over CapeDwarf (long chain I know :-)) As you can see, I do cleanup afterwards, but ... I run the same test twice, via ARQ, where I leave the name generation to ARQ: 10:49:08,684 INFO [org.jboss.as.server.deployment] (MSC service thread 1-1) JBAS015876: Starting deployment of "e9b7626a-361c-417d-80d5-b9e46af09f48.war" 10:49:10,466 INFO [org.jboss.as.capedwarf.deployment.CapedwarfInitializationProcessor] (MSC service thread 1-4) Found GAE / CapeDwarf deployment: deployment "e9b7626a-361c-417d-80d5-b9e46af09f48.war" 2nd run: 10:51:20,686 INFO [org.jboss.as.server] (management-handler-thread - 5) JBAS018559: Deployed "6de03e61-ceb9-49d7-ad48-0f9edcc150ce.war" Caused by: org.jboss.modules.ModuleNotFoundException: deployment.e9b7626a-361c-417d-80d5-b9e46af09f48.war:main at org.jboss.modules.ModuleLoader.loadModule(ModuleLoader.java:206) [jboss-modules.jar:1.1.2.GA] at org.jboss.marshalling.ModularClassResolver.resolveClass(ModularClassResolver.java:106) As you can see, it tries to load some data from 1st deployment / test. But since that's already undeployed, it's not found. Shouldn't that JPA delete in finally block clean all stale data? Trying to reproduce this now with smaller dep chain. :-) --- public void testSaveAndQuery() throws Throwable { final Client client = new Client(); EMAction<Long> ema1 = new EMAction<Long>() { public Long go(EntityManager em) throws Throwable { client.setUsername("alesj"); client.setPassword("password"); client.setEmail(&quot;aj(a)jboss.com&quot;); em.persist(client); return client.getId(); } }; run(ema1); try { final Long id = client.getId(); Assert.assertNotNull("Null client id", id); EMAction<Client> ema2 = new EMAction<Client>() { public Client go(EntityManager em) throws Throwable { Query q = em.createQuery("select from Client c where c.username = :username"); q.setParameter("username", "alesj"); @SuppressWarnings("unchecked") List<Client> clients = q.getResultList(); return (clients.isEmpty()) ? null : clients.get(0); } }; Client c = run(ema2, false); Assert.assertNotNull(c); Assert.assertEquals(id, c.getId()); Assert.assertEquals("alesj", c.getUsername()); Assert.assertEquals("password", c.getPassword()); EMAction<Client> ema3 = new EMAction<Client>() { public Client go(EntityManager em) throws Throwable { return em.find(Client.class, id); } }; c = run(ema3, false); Assert.assertNotNull(c); Assert.assertEquals(id, c.getId()); Assert.assertEquals("alesj", c.getUsername()); Assert.assertEquals("password", c.getPassword()); } finally { EMAction<Integer> delete = new EMAction<Integer>() { public Integer go(EntityManager em) throws Throwable { Query query = em.createQuery("delete from Client c where c.id = :id"); query.setParameter("id", client.getId()); return query.executeUpdate(); } }; Assert.assertTrue(1 == run(delete)); } }
