[jboss-jira] [JBoss JIRA] (WFLY-875) Singletons don't respect @TransactionAttribute/deployment descriptor in @PostConstruct.

Singletons don't respect @TransactionAttribute/deployment descriptor in @PostConstruct. --------------------------------------------------------------------------------------- Key: WFLY-875 URL: https://issues.jboss.org/browse/WFLY-875 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: EJB Environment: JBoss 7.1.1 Reporter: Sławomir Wojtasiak Assignee: Stuart Douglas Labels: rhq Attachments: jboss-as-helloworld-singleton.war Singletons don't respect any transaction attributes for their @PostConstruct methods and invokes them always with REQUIRED_NEW semantics. Following part of code is responsible for hardcoding these values for registered _SingletonLifecycleCMTTxInterceptor_ factories: {code:title=org.jboss.as.ejb3.component.singleton.SingletonComponentDescription.java|borderStyle=solid} @Override public void configure(final DeploymentPhaseContext context, final ComponentDescription description, final ComponentConfiguration configuration) throws DeploymentUnitProcessingException { configuration.addPostConstructInterceptor(new SingletonLifecycleCMTTxInterceptor.Factory(TransactionAttributeType.REQUIRES_NEW), InterceptorOrder.ComponentPostConstruct.TRANSACTION_INTERCEPTOR); configuration.addPreDestroyInterceptor(new SingletonLifecycleCMTTxInterceptor.Factory(TransactionAttributeType.REQUIRES_NEW), InterceptorOrder.ComponentPreDestroy.TRANSACTION_INTERCEPTOR); if(description.isPassivationApplicable()) { configuration.addPrePassivateInterceptor(new SingletonLifecycleCMTTxInterceptor.Factory(TransactionAttributeType.REQUIRES_NEW), InterceptorOrder.ComponentPassivation.TRANSACTION_INTERCEPTOR); configuration.addPostActivateInterceptor(new SingletonLifecycleCMTTxInterceptor.Factory(TransactionAttributeType.REQUIRES_NEW), InterceptorOrder.ComponentPassivation.TRANSACTION_INTERCEPTOR); } configuration.addTimeoutViewInterceptor(TimerCMTTxInterceptor.FACTORY, InterceptorOrder.View.CMT_TRANSACTION_INTERCEPTOR); } {code} EJB 3.1 specification says, REQUIRED, REQUIRED_NEW and NOT_SUPPORTED attributes should be supported, where in case of REQUIRED a semantic of REQUIRED_NEW trancation attribute should be used: {panel:title=4.8.3 Transaction Semantics of Initialization and Destruction| borderStyle=dashed| borderColor=#ccc| titleBGColor=#F7D6C1| bgColor=#FFFFCE} PostConstruct and PreDestroy methods of Singletons with container-managed transactions are transactional. From the bean developer’s view there is no client of a PostConstruct or PreDestroy method. A PostConstruct or PreDestroy method of a Singleton with container-managed transactions has transaction attribute REQUIRED, REQUIRES_NEW, or NOT_SUPPORTED (Required , RequiresNew, or NotSupported if the deployment descriptor is used to specify the transaction attribute). _Note that the container must start a new transaction if the REQUIRED (Required) transaction attribute is used. This guarantees, for example, that the transactional behavior of the PostConstruct method is the same regardless of whether it is initialized eagerly at container startup time or as a side effect of a first client invocation on the Singleton. The REQUIRED transaction attribute value is allowed so that specification of a transaction attribute for the Singleton PostConstruct/PreDestroy methods can be defaulted._ {panel} So there is not a problem with REQUIRED and REQUIRED_NEW transaction attributes, but NOT_SUPPORTED attribute is just not supported :)
