[jboss-jira] [JBoss JIRA] (WFLY-5235) CDI interceptors are not called when invoking observer method

[Dirk Weil (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-5235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13111464#comment-13111464 ] 

Dirk Weil commented on WFLY-5235:
---------------------------------

I finally found some time to dig into the problem a little bit more: If the observer method is private, interceptors are not called. With non-private methods, interceptors are working as expected. This behaviour has changed from WildFly 8.2.0 to 9.0.1. I didn't check WildFly 10.

I tried to find out from the specification, if interceptors should be called when invoking private methods, but found no unmistakable statement. If someone could clarify that, I would be very thankful.

I can imagine, that the methods intercepted must be non-private. But if that is the case, an appropriate exception should be thrown, if they are private.

The problem can be reproduced with this demo: https://github.com/dirkweil/wildfly-cdiscopeinit-demo. If you build the application (just run mvn) and deploy the resulting war file onto WildFly 8, no exception arises. If using WildFly 9 a TransactionRequiredException is thrown in the observer method de.gedoplan.beantrial.wildflycdiscopeinit.service.InitTestDataService.createTestData.

> The following code runs with an active transaction on WFLY 8.2.0, but failes with an TransactionRequiredException on WFLY 9.0.1:
> @ApplicationScoped
> public class InitCocktailDemoDataService
> {
>   @PersistenceContext
>   private EntityManager entityManager;
>   @Transactional
>   private void createDemoData(@Observes @Initialized(ApplicationScoped.class) Object event)
>   {
>         this.entityManager.merge(someEntity);
>       }
> It seems that interceptors aren't called at all - at least for observers of scope lifecycle events.
