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.
We now gracefully fall back to reflective invocation of the application event listener shouldHandle(…) method if we're not on Spring Framework 6.2. If we are, we invoke the newly introduced method directly.
This allows projects to upgrade to Spring Modulith 1.1 without necessarily upgrading to Boot 3.2.
DelegatingEventExternalizer.externalize(…) flavors now return a CompletableFuture to allow the target APIs to use asynchronous message sending and to transparently return a result from those invocations.
Removed the inclusion of the spring-modulith-runtime artifact from the …-starter-core one to avoid issues in native images in a Spring Modulith default setup. As the artifact is still needed to support ApplicationModuleInitializer implementations, we now explicitly check for the presence of those and verify the artifact is actually available and hint the user at explicitly adding it if missing.
We now expose spring.modulith.events.externalization.enabled that can be set to false to disable the event externalization completely. Useful in test cases, for example.
We now skip configuration classes for observability-related proxying as it's hard to detect those during the ProxyFactory setup to configure target class proxying. Also, configuration classes are usually no targets of inter-module communication and thus don't need to be observed at all.
We now skip infrastructure role beans during the processing of beans that could be subject to inter-module interaction observability. Previously, we could accidentally trigger a dependency cycle if the ModuleTracingBeanPostProcessor triggered the initial creation of AutoConfigurationPackages as that would then trigger the PostProcessor in turn which would try to lookup the ACP bean again to determine whether it should post process that to apply observability.
We now create artificial root application modules for all root packages to detect violations (for example, types located in root packages referring to module-internal types).
Prior to this commit, the lookup for an ApplicationModule would find modules solely depending on the reference string starting with the base package. That means that a module with base package com.acme.foo, a request for com.acme.foobar would've resulted in a positive match, which of course is wrong.
We now match against either the module's base package or against the reference starting with the base package followed by a dot.
We now reflectively invoke ApplicationListenerMethodAdapter.shouldHandle(…) when selecting event listeners to make sure that conditions defined in, for example, @TransactionalEventListener are considered before registering an event publication.
