The question is: is this something we really want to be fixing?

What is the problem with JDG Helloworld quickstart piggy backing on the provided Infinispan JAR by EAP? I'd expect that to work without problems.

Infinispan library breaks Hibernate 2LC with java.lang.ClassCastException: org.infinispan.remoting.ReplicationQueueImpl cannot be cast to org.infinispan.remoting.ReplicationQueue ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: ISPN-3496 URL: https://issues.jboss.org/browse/ISPN-3496 Project: Infinispan Issue Type: Bug Affects Versions: 5.2.1.Final Environment: EAP 6.1.0 and 6.1.1. This is a regression since EAP 6.0.1 Reporter: Martin Gencur Assignee: Galder Zamarreño Priority: Critical Labels: jdg62blocker Fix For: 6.0.0.Beta2 A WAR deployment containing its own infinispan (such as JDG helloworld quickstart) and also having persistence.xml with second level cache enabled fails to deploy on EAP 6.1 HA configuration (standalone-ha.xml or standalone-full-ha.xml) Version-Release number of selected component (if applicable): EAP 6.1.0, EAP 6.1.1.ER4. Note: This does not happen with EAP 6.0.1 so it's a regression. Steps to Reproduce: 1. Get JDG 6.1 helloworld-jdg quickstart (or see the attachment) 2. Add persistence.xml with 2lc, e.g.: {code} <?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0"> <persistence-unit name="entityManager"> <jta-data-source>java:jboss/datasources/ExampleDS</jta-data-source> <properties> <property name="hibernate.hbm2ddl.auto" value="create-drop"/> <property name="hibernate.cache.use_second_level_cache" value="true"/> <property name="hibernate.cache.use_query_cache" value="true"/> </properties> </persistence-unit> </persistence> {code} 3. deploy the helloworld-jdg on standalone-ha.xml or standalone-full-ha.xml configuration of EAP 6.1. This happens also when standalone.xml file is used to start EAP. The resulting error: {code} 10:26:20,759 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 53) MSC000001: Failed to start service jboss.persistenceunit."jboss-as-helloworld-jdg.war#entityManager": org.jboss.msc.service.StartException in service jboss.persistenceunit."jboss-as-helloworld-jdg.war#entityManager": javax.persistence.PersistenceException: [PersistenceUnit: entityManager] Unable to build EntityManagerFactory at org.jboss.as.jpa.service.PersistenceUnitServiceImpl$1.run(PersistenceUnitServiceImpl.java:103) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [rt.jar:1.7.0_25] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [rt.jar:1.7.0_25] at java.lang.Thread.run(Thread.java:724) [rt.jar:1.7.0_25] at org.jboss.threads.JBossThread.run(JBossThread.java:122) [jboss-threads-2.1.0.Final-redhat-1.jar:2.1.0.Final-redhat-1] Caused by: javax.persistence.PersistenceException: [PersistenceUnit: entityManager] Unable to build EntityManagerFactory at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:930) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:904) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:92) at org.jboss.as.jpa.service.PersistenceUnitServiceImpl.createContainerEntityManagerFactory(PersistenceUnitServiceImpl.java:200) at org.jboss.as.jpa.service.PersistenceUnitServiceImpl.access$600(PersistenceUnitServiceImpl.java:57) at org.jboss.as.jpa.service.PersistenceUnitServiceImpl$1.run(PersistenceUnitServiceImpl.java:99) ... 4 more Caused by: org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.spi.CacheImplementor] at org.hibernate.service.internal.AbstractServiceRegistryImpl.createService(AbstractServiceRegistryImpl.java:186) at org.hibernate.service.internal.AbstractServiceRegistryImpl.initializeService(AbstractServiceRegistryImpl.java:150) at org.hibernate.service.internal.AbstractServiceRegistryImpl.getService(AbstractServiceRegistryImpl.java:131) at org.hibernate.internal.SessionFactoryImpl.<init>(SessionFactoryImpl.java:264) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1762) at org.hibernate.ejb.EntityManagerFactoryImpl.<init>(EntityManagerFactoryImpl.java:94) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:920) ... 9 more Caused by: org.hibernate.cache.CacheException: Unable to start region factory at org.hibernate.cache.infinispan.InfinispanRegionFactory.start(InfinispanRegionFactory.java:323) at org.hibernate.internal.CacheImpl.<init>(CacheImpl.java:70) at org.hibernate.engine.spi.CacheInitiator.initiateService(CacheInitiator.java:40) at org.hibernate.engine.spi.CacheInitiator.initiateService(CacheInitiator.java:35) at org.hibernate.service.internal.SessionFactoryServiceRegistryImpl.initiateService(SessionFactoryServiceRegistryImpl.java:91) at org.hibernate.service.internal.AbstractServiceRegistryImpl.createService(AbstractServiceRegistryImpl.java:176) ... 15 more Caused by: java.lang.ClassCastException: org.infinispan.remoting.ReplicationQueueImpl cannot be cast to org.infinispan.remoting.ReplicationQueue at org.infinispan.configuration.cache.LegacyConfigurationAdaptor.adapt(LegacyConfigurationAdaptor.java:306) at org.infinispan.manager.DefaultCacheManager.defineConfiguration(DefaultCacheManager.java:468) at org.infinispan.manager.DefaultCacheManager.defineConfiguration(DefaultCacheManager.java:443) at org.jboss.as.clustering.infinispan.DefaultEmbeddedCacheManager.defineConfiguration(DefaultEmbeddedCacheManager.java:77) at org.hibernate.cache.infinispan.InfinispanRegionFactory.defineGenericDataTypeCacheConfigurations(InfinispanRegionFactory.java:492) at org.hibernate.cache.infinispan.InfinispanRegionFactory.start(InfinispanRegionFactory.java:318) ... 20 more 10:26:20,968 ERROR [org.jboss.as.server] (management-handler-thread - 4) JBAS015870: Deploy of deployment "jboss-as-helloworld-jdg.war" was rolled back with the following failure message: {"JBAS014671: Failed services" => {"jboss.persistenceunit.\"jboss-as-helloworld-jdg.war#entityManager\"" => "org.jboss.msc.service.StartException in service jboss.persistenceunit.\"jboss-as-helloworld-jdg.war#entityManager\": javax.persistence.PersistenceException: [PersistenceUnit: entityManager] Unable to build EntityManagerFactory Caused by: javax.persistence.PersistenceException: [PersistenceUnit: entityManager] Unable to build EntityManagerFactory Caused by: org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.spi.CacheImplementor] Caused by: org.hibernate.cache.CacheException: Unable to start region factory Caused by: java.lang.ClassCastException: org.infinispan.remoting.ReplicationQueueImpl cannot be cast to org.infinispan.remoting.ReplicationQueue"}} {code}
