The package o.s.messaging.handler.annotation.support was missing
@NonnullApi and @NonNullFields. This commit corrects that and also
adds @Nullable to methods and arguments as needed to address
warnings.
This commit makes the 3 existing InvocableHandlerMethod types more
consistent and comparable with each other.
1. Use of consistent method names and method order.
2. Consistent error formatting.
3. Explicit for loops for resolving argument values in webflux variant
because that makes it more readable, creates less garabage, and it's
the only way to bring consistency since the other two variants cannot
throw exceptions inside Optional lambdas (vs webflux variant which can
wrap it in a Mono).
4. Use package private HandlerMethodArgumentComposite in webflux
variant in order to pick up the resolver argument caching that the
other two variants have.
5. Polish tests.
6. Add missing tests for messaging variant.
Tomcat and Jetty integration tests were moved out of spring-messaging
a very long time ago (before 4.0), but the dependencies remained
unnoticed until now.
This was a package private class in spring-messaging since 5.0, and was
recently made public in 5.1. This commit promotes it to spring-core
where it belongs next to all other ListenableFuture support classes.
Follow-up refactoring for SPR-17336
Collapse the package private AbstractMonoToListenableFutureAdapter into
its only sub-class MonoToListenableFutureAdapter. There is no need for
such an abstract class that makes it possible to adapt from one source
to a different target type. That's already covered by
ListenableFutureAdapter.
Follow-up refactoring for SPR-17336.
Empty Maps are preferably initialized without capacity (not initializing them at all or lazily initializing with default capacity when needed).
Issue: SPR-17105
This commit adds support for single-value reactive types in
@MessageMapping by converting them using ReactiveAdapterRegistry
and MonoToListenableFutureAdapter.
MonoToListenableFutureAdapter previously package private and used only
in org.springframework.messaging.tcp.reactor has been moved to
org.springframework.messaging.support and made public in order to be
used by ReactiveReturnValueHandler as well.

Update all classes so that inner classes are always last. Also
ensure that utility classes are always final and have a private
constructor and make exceptions final whenever possible.

Prior to this commit, the generated POMs for Spring Framework modules
would contain unneeded/harmful information from the Spring Framework
build:
1. The BOM imports applied to each module by the dependency
management plugin, for example for Netty or Reactor Netty.
Spring should not export that opinion to its POMs.
2. The exclusion of "org.slf4:jcl-over-slf4j" from *all* dependencies,
which made the POMs much larger than necessary and suggested to
developers that they should exclude it as well when using all those
listed dependencies. In fact, only Apache Tiles currently brings that
transitively.
This commit removes that information from the POMs.
The dependencyManagement Gradle plugin is disabled for POM generation
and we manually resolve the dependency versions during the generation
phase.
The Gradle build is streamlined to exclude "org.slf4:jcl-over-slf4j"
only when necessary.

After the recent changes to expose configuring TcpOperations, it no
longer makes sense to automatically log the relayHost/Port since that's
mutually exclusive with a custom TcpOperations.
Instead we delegate to TcpOperations.toString().
Issue: SPR-16801
HandlerMethodReturnValueHandlerComposite and
AbstractMethodMessageHandler iterate using index over collections
implementing RandomAccess to avoid unnecessary iterators.
Rather than create a new EvaluationContext instance per evaluation, we
now create a statically shared instance, without the root object in it,
and re-use it for all evalutations.
As of 4.3.13 MappingJackson2MessageConverter uses the MethodParameter
hint to obtain generic type information but it needs to be careful, and
nest one level, if the target parameter type has a Message wrapper.
Issue: SPR-16486
After this commit DefaultUserDestinationResolves no longer looks at
whether AntPathMatcher is configured with "." as separator and rather
expects to be explicitly told whether to keep the leading slash in
translated destinations which actually depends on what the message
broker supports (e.g. RabbitMQ "/", Artemis ".") or how it is
configured (simple broker could be either way).
There is also a minor improvement in SimpMessagingTemplate to ensure
user destinations are correctly formed based on what the
DefaultUserDestinationResolver expects. When using "." as separtor it
allows sending messages to "queue.q1" rather than "/queue.q1".
Issue: SPR-16275
SimpMessageTypeMessageCondition was lenient in matching the message
type, essentially matching on any non-null message type with an exact
match given a preference only in comparing mulitple matches.
This commit modifies matching logic to look for an exact match.

Also, ChannelRegistration.setInterceptors is deprecated now: in favor of a fluently named interceptors(...) method which is documented to add the given interceptors to the channel's current list.

Issue: SPR-15976
This commit introduces the following changes.
1) It adds a new Spring @NonNull annotation which allows to apply
@NonNullApi semantic on a specific element, like @Nullable does.
Combined with @Nullable, it allows partial null-safety support when
package granularity is too broad.
2) @Nullable and @NonNull can apply to ElementType.TYPE_USE in order
to be used on generic type arguments (SPR-15942).
3) Annotations does not apply to ElementType.TYPE_PARAMETER anymore
since it is not supported yet (applicability for such use case is
controversial and need to be discussed).
4) @NonNullApi does not apply to ElementType.FIELD anymore since in a
lot of use cases (private, protected) it is not part for the public API
+ its usage should remain opt-in. A dedicated @NonNullFields annotation
has been added in order to set fields default to non-nullable.
5) Updated Javadoc and reference documentation.
Issue: SPR-15756
This commit applies the Dependency Management Plugin to modules that
require it; right now Spring Framework is importing BOMs for Netty and
Reactor dependencies only.
Instead of applying those BOMs to all modules, they're applied only
where they're needed.
Issue: SPR-15885
The main `build.gradle` file contains now only the common build
infrastructure; all module-specific build configurations have
been moved to their own build file.
Issue: SPR-15885
Includes general streamlining of dependency declarations with reduced version variables, direct use of EclipseLink 2.7 and its implicit JPA 2.2 dependency in spring-orm, mixed use of Hibernate 5.2.10 and 5.1.10 for integration tests, as well as an upgrade to Jetty 9.4.7 RC0 and a downgrade to Groovy 2.4.12 (since Groovy 2.5 won't be final in time for Spring Framework 5.0).

Bean-derived null values may still get passed into bean properties and injection points but only if those are declared as non-required. Note that getBean will never return null; a manual bean.equals(null) / "null".equals(bean.toString()) check identifies expected null values now. This will only ever happen with custom FactoryBeans or factory methods returning null - and since all common cases are handled by autowiring or bean property values in bean definitions, there should be no need to ever manually check for such a null value received from getBean.
