Introduce @PackageInfo annotation to allow marking a types as alternative to Java's native package-info.java so that annotation lookups on a JavaPackage will also find annotations placed on that type. Useful to declare package scoped metadata like @ApplicationModule and @NamedInterface for languages that do not support packages well enough (read: Kotlin).
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 create artificial root application modules for all root packages to detect violations (for example, types located in root packages referring to module-internal types).
The default for @ApplicationModule(allowedDependencies) is now a single element list with a dedicated token we recognize as "all dependencies allowed". This allows users to declare an empty array explicitly to disallow any outgoing dependencies for an application module. Previously, such a declaration would have allowed any dependency.
We now verify detected dependencies against optionally explicitly defined ones. Those can refer to named interfaces (via the "moduleName :: namedInterfaceName" syntax). If such an allowed dependency is defined, all dependencies towards other named interfaces (also the unnamed one) are rejected.
Some Javadoc polishing.
