We now guard the annotation predicate for @Generated behind a classpath check to avoid a NoClassDefFoundError on previous versions of Spring Framework.
We now properly wrap the null value returned as a result from the RabbitMQ event externalization into a CompletableFuture. Tightened test case to prevent regressions going forward.
The default EventPublicationRegistry previously erroneously called find*In*completePublications(), i.e. returned incomplete publications when it was supposed to look up the completed ones. To be able to do the latter we need to extend EventPublicationRepository and introduce a query execution for all completed publications.
As we'd normally only chance API in major versions, but the bugfix needing to go into a bugfix release, the new method is introduced as default method rejecting the execution in case a currently existing repository implementation does not implement it. This allows us to adapt the implementations we ship to support the bugfix, but will require other implementations to ship an adapted version. This means we can ship a release that's not breaking assuming one of the official store implementations is used.
Spring Boot configures Hibernate Validator in a way that the latter looks up the components it needs to instantiate via the Spring container. That in turn then creates prototype instances of the types requested. This means, implementations of e.g. ConstraintValidator do not need to be explicitly marked as Spring beans, but could still declare dependencies to other Spring beans. If such a dependency crosses a module boundary, we currently fail to detect that implicitly established module dependency.
This is now fixed by considering ConstraintValidator implementations Spring beans implicitly in out bootstrap dependency analysis.
We now explicitly exclude classes generated by Spring AOT in the architectural model. For technical reasons, they might introduce dependencies to application components considered module internals otherwise. Also, proxies generated do not need to be considered either.
We now explicitly handle CompletableFuture instances returned from transactional event listeners by registering the completion handlers only on success, the debug logging on failure and immediately return the decorated instance.
Previously, a failed CompletableFuture instance would still have the publication marked completed as it doesn't cause any exception being thrown and thus ultimately ending up in the code path that issues the completion.
We now propagate potentially occurring exceptions in CompletionRegisteringAdvisor to make sure the standard exception handling facilities kick in, both for synchronous and asynchronous listener invocations.
This implies that during republication we need to handle exceptions to make sure that failing synchronous listeners to not prevent the submission of subsequent publications. We currently log such exceptions into error.
We now register a BeanFactoryInitializationAotProcessor to generate the actuator endpoint content representing the application module structure at AOT processing time. That file is then preferred over bootstrapping an ApplicationModules instance when bootstrapping the endpoint.
We now skip the defaulting to wait of the pool shutdown termination on Spring Framework 6.1, as on that, pools implement Lifecycle and we need to wait for complete shutdown during Lifecycle.stop() already and setting the flag would delay that wait to the actual destruction phase.
The maintain general compatibility with Spring Framework 6.0, we issue a few reflective inspections on ApplicationListenerMethodAdapter. To make this work properly in native images, we now register those methods for GraalVM reflection.
If Spring Modulith packages were explicitly configured as autoconfiguration or entity scan packages, the test autoconfiguration would fail as it previously attempted to manipulate an immutable list. We now create a copy of that list to fix this.
