Kotlin lambdas mostly used to configure endpoints in DSL manner
are not really Java lambdas, but rather anonymous classes implementing
respective Java interfaces.
While in most cases such classes carry generic info for their method impls
properly in Java, it is somehow doesn't work well for `GenericHandler`
implemented by Kotlin lambdas
* Wrap provided `GenericHandler` in the `BaseIntegrationFlowDefinition.handle()`
into a Java lambda and call `handle()` recursively to carry an expected type to
the `LambdaMessageProcessor`
* Fix `LambdaMessageProcessor` to handle `ClassUtils.isKotlinUnit()` result of
an invocation as a `null` reply
**Cherry-pick to `5.4.x` & `5.3.x`**
* GH-3521: Delayer: schedule release task with TX
Fixes https://github.com/spring-projects/spring-integration/issues/3521
There is a race condition when transactional `MessageStore` is used
for `DelayHandler`, so the message is not visible for reads until after TX is
committed, but a scheduled release task may be already ready after delay
* Register a `TransactionSynchronization` with scheduling a releasing task
when TX is committed

* Rely on `MProducerSupport.active` for `Flux`
* Fix `MessageProducerSupport` to extract an `active` flag and set it before
`isRunning` - the `Flux` subscription relies on the `takeWhile()`
where in case of `autoStartup = false` we will never start consume because
it is set to `true` already after `doStart()`
* Refactor all the `MessageProducerSupport` implementation with similar
`active` state to use already one from the super class
**Cherry-pick to 5.3.x**
* * Remove `MessageProducerSupport.setActive()`
to not let to mutate it from the implementations
* Set `active` to `false` in the `destroy()`
* Clean up and fix typos in the affected `JmsMessageDrivenEndpoint`
* * Pull `active` flag down to the `AbstractEndpoint`
* Set `active = true` in the `start()` before calling `doStart()`
* Do same for `active = false` in the `stop()`
* Clean up `AbstractEndpoint` impls to not call `doStart/doStop` for nothing
* Refactor endpoints to rely on the `active` state from the `AbstractEndpoint`
not their own
The `InboundChannelAdapterAnnotationPostProcessor` doesn't use a bean method name
when it parses a `Supplier` bean and only uses a configuration class name + `get`
for method part
* Fix `InboundChannelAdapterAnnotationPostProcessor` to also include a bean method
name into the final bean name for the `MethodInvokingMessageSource` based on
the `Supplier` bean
* Modify `ReactiveInboundChannelAdapterTests` to add one more `Supplier` with the
`@InboundChannelAdapter` to ensure that configuration is still valid after the fix

See SO for more info:
https://stackoverflow.com/questions/64456946/handle-exceptions-errors-other-than-messagingexception-ie-other-error-excepti
In the versions before `5.2.x` the `Error` was wrapped to the `MessagingException`
in the `AbstractRequestHandlerAdvice` and this one was handled properly
on the gateway level with its `errorChannel` configured
* Fix `MessagingGatewaySupport` to catch all the `Throwable` and try to send them as `ErrorMessage`
to the `errorChannel`.
Otherwise unwrap returned `MessagingException` and re-throw an `Error` as is to keep
the current behavior for non-handled exceptions
* Do not wrap `Error` into a `MessagingException` and re-throw as is if there is no `errorChannel`
**Cherry-pick to 5.3.x & 5.2.x**
If there is a `MeterRegistry` bean (any) in the application context,
we add a `MicrometerMetricsCaptor` bean which populates meters further
from the components.
In some case we may load a `MicrometerMetricsCaptor` bean too early
so, not all the stuff around `MeterRegistry` maybe ready.
See Spring Boot and its `MetricsAutoConfiguration`
* Fix the `MicrometerMetricsCaptorRegistrar` the way to rely on the
`ObjectProvider<MeterRegistry>` instead
* Add package protected ctor to the `MicrometerMetricsCaptor` to
provide a target `MeterRegistry` on demand
All of that will ensure that we use an already post-processed `MeterRegistry`
including Spring Boot auto-configuration
**Cherry-pick to 5.3.x & 5.2.x**
* GH-3376: Remove gauges on application ctx close
Fixes https://github.com/spring-projects/spring-integration/issues/3376
The `MeterRegistry` may request meters on application shutdown.
The gauges for channels, handlers and message sources don't make sense
at the moment since all those beans are going to be destroyed.
* Remove gauges for channel, handler and message source numbers from the
`IntegrationManagementConfigurer.destroy()`
**Cherry-pick to 5.3.x & 5.2.x**
* * Add `MicrometerImportSelector` to conditionally load
a `MicrometerMetricsCaptorConfiguration` when `MeterRegistry`
is on class path.
* Make `MicrometerMetricsCaptorConfiguration.integrationMicrometerMetricsCaptor()`
bean dependant on the `ObjectProvider<MeterRegistry>`
* Make `IntegrationManagementConfiguration.managementConfigurer()`
dependant on the `ObjectProvider<MetricsCaptor>`.
This way the `IntegrationManagementConfigurer` is destroyed before
`MeterRegistry` when application context is closed
* Deprecate `MicrometerMetricsCaptor.loadCaptor()` in favor of
`@Import(MicrometerImportSelector.class)`
* * Add `MicrometerMetricsCaptorRegistrar` to register a `MICROMETER_CAPTOR_NAME`
bean when `MeterRegistry` is on class path and no `MICROMETER_CAPTOR_NAME` bean yet.
* Make `IntegrationManagementConfiguration.managementConfigurer()`
dependant on the `ObjectProvider<MetricsCaptor>`.
This way the `IntegrationManagementConfigurer` is destroyed before
`MeterRegistry` when application context is closed
* Deprecate `MicrometerMetricsCaptor.loadCaptor()` in favor of
`@Import(MicrometerMetricsCaptorRegistrar.class)`
* Fix test to make a `MeterRegistry` bean as `static` since
`@EnableIntegrationManagement` depends on this bean definition now

Fixes https://github.com/spring-projects/spring-integration/issues/3374
An internal `ClassPathScanningCandidateComponentProvider` instance in the `IntegrationComponentScanRegistrar`
does not propagate a provided `registry`.
* Implement `getRegistry()` on the internal `ClassPathScanningCandidateComponentProvider` to propagate
a provided into the `registerBeanDefinitions()` a `BeanDefinitionRegistry`
* Add `@Conditional` on some scanned `@MessagingGateway` in the `EnableIntegrationTests`
**Cherry-pick to 5.3.x & 5.2.x**

The `QueueChannel` provides a current size and remaining capacity metrics
* Add Micrometer gauges into `QueueChannel` to expose the current values
of the size and remaining capacity
**Cherry-pick to 5.3.x, 5.2.x & 5.1.x**
* * Revert `@SuppressWarnings("unchecked")` for test

* GH-3344: Treat kotlin.Unit return as null in MMIH
Fixes https://github.com/spring-projects/spring-integration/issues/3344
When function lambda doesn't return anything (e.g. a `void` method call is the last one),
Kotlin produces a `kotlin.Unit` instance as a return value which is not null and produced
as a reply message payload.
* Fix `MessagingMethodInvokerHelper` to treat a `kotlin.Unit` as `null` for reply
making Kotlin lambdas working the same way as Java lambdas when we don't return anything
from from there
**Cherry-pick to `5.3.x`**
* * Introduce `ClassUtils.isKotlinUnit(Class)` API;
use it in the `MessagingMethodInvokerHelper` instead of
`.getName().equals()`
* * Fix since on new `isKotlinUnit()` API
Related to https://stackoverflow.com/questions/62761903/spring-integration-reactive-streams-support-exception-in-creating-a-reactive
The `MessagingGatewaySupport` creates an internal endpoint
for consuming messages from the provided `replyChannel`.
The endpoint type depends on the channel type.
The `ReactiveStreamsConsumer` was missing a `BeanFactory` injection
causing an error when `ReactiveStreamsConsumer` tries to extract a default `ErrorHandler`
from `BeanFactory`
* Refactor `MessagingGatewaySupport` to inject a `BeanFactory` to all
the possible correlator endpoints.
Also always call `afterPropertiesSet()` for all of them
**Cherry-pick to 5.3.x & 5.2.x**
Close the pool so that any sessions returned after the factory is
`destroy()`ed are closed.
* Call `removeAllIdleItems()` in `close()`.
* Close sessions in `SftpStreamingMessageSourceTests`.
**cherry-pick to all supported branches**
Fixes https://github.com/spring-projects/spring-integration/issues/3288
* For better end-user experience with Kotlin DSL and get a gain from
existing `Transformer` implementations add a `transform(Transformer)`
EI-method into the `KotlinIntegrationFlowDefinition`
* Also add `filter(MessageSelector)` for any out-of-the-box `MessageSelector`
**Cherry-pick to 5.3.x**
Fixes https://github.com/spring-projects/spring-integration/issues/3266
It turns out that `AnnotationGatewayProxyFactoryBean.onInit()` implementation
parses a `@MessagingGateway` attributes ignoring possible properties
population by setters.
This way a Java DSL `GatewayProxySpec` becomes useless since all
its options are overridden by default values from a synthesized
`@MessagingGateway`.
Also it is inconsistency when we declare an `AnnotationGatewayProxyFactoryBean`
as regular bean, but then called setters are ignored
* Add `protected` getters into `GatewayProxyFactoryBean` for all
the properties which can be overridden by annotation attributes
* Fix `AnnotationGatewayProxyFactoryBean` to consult with those getters
before populating a property with value from the annotation
**Cherry-pick to 5.2.x**
* Introduce a `ReceiveMessageAdvice`
* Deprecate an `AbstractMessageSourceAdvice` in favor of
`default` method in the `MessageSourceMutator`
* Move a `applyReceiveOnlyAdviceChain()` logic into the `AbstractPollingEndpoint`:
now both `PollingConsumer` and `SourcePollingChannelAdapter` can use
`ReceiveMessageAdvice`
* Introduce a `SimpleActiveIdleReceiveMessageAdvice` based already
on the `ReceiveMessageAdvice` and deprecate a `SimpleActiveIdleMessageSourceAdvice`
which is fully replaceable with newly introduced `SimpleActiveIdleReceiveMessageAdvice`
* Add `@SuppressWarnings("deprecation")` for those out-of-the-box `ReceiveMessageAdvice`
implementation which still use an `AbstractMessageSourceAdvice` for
backward compatibility
* Document a new feature and give the `MessageSourceMutator` a new meaning
* * Fix language in the `polling-consumer.adoc`
* Add `ReactiveMessageSourceProducer`
The `ReactiveMessageSourceProducer` wraps a provided `MessageSource`
into a `Flux` for subscription in the `subscribeToPublisher(Publisher<? extends Message<?>>)`
to make a source polling feature fully based on a reactive, on demand solution
* Introduce a `IntegrationReactiveUtils` replacing existing `MessageChannelReactiveUtils`
with more functionality
* Replace a deprecated `MessageChannelReactiveUtils` with a new `IntegrationReactiveUtils`
* Test and document the feature
* * Fix Docs typos
* * Remove unused imports from `MessageChannelReactiveUtils`
* * Fix JavaDoc copy/paste artifact
- add a module to suppress legacy metrics from the Integration Graph
- move graph tests package to match src/main
Fix missed deprecation and checkstyle.
More deprecations and remove GraphLegacyStatsNullModule.
* Revert GRAPH_VERSION.
* Fix JavaDocs warnings
* Fix `MBeanExporterParserTests`
Fixes https://github.com/spring-projects/spring-integration/issues/2788
* Introduce a `MessageProducerSupport.subscribeToPublisher(Publisher<Message<?>>)`
for components which produces `Flux` for data from their source
* Such a component is auto-stopped when subscription to that `Publisher` is canceled
* Implement a `MongoDbChangeStreamMessageProducer` based on the reactive support for
in Spring Data MongoDb
* Implement a Java DSL for `MongoDbChangeStreamMessageProducer`
* Disable a test for change stream since it requires server of version 4.x started with 'replSet' option
* Add `MongoHeaders` for change stream events
* Change `MessageProducerSupport` to use a `takeWhile((message) -> isRunning())`
instead of storing a `subscription` from a callback
* Document new features
* Remove trailing whitespaces
* Doc Polishing.

Previously, methods with the same name as `Lifecycle` methods were unconditionally ignored.
- Use logic similar to `ControlBusMethodFilter` to explicitly compare the candidate Method
to those on `Paused` and `Lifecycle` and only ignore those.
- Explicitly disallow these methods when named - previously the check was only performed
if no method name was supplied.
* - reinstate `Pausable/Lifecycle` methods if explicitly requested.
- log `Pausable` methods that are not candidates.
* - Fix typo in test method.
**Cherry-pick to 5.2.x**
* Add more Kotlin DSL for sub-flows
* Introduce `KotlinSplitterEndpointSpec`, `KotlinEnricherSpec` &
`KotlinFilterEndpointSpec` to avoid an explicit use of `IntegrationFlow` usage
from Kotlin DSL
* Fix `AbstractKotlinRouterSpec` to extend `ConsumerEndpointSpec` for access
to more endpoint options as it is with Java DSL for similar specs
* Introduce a `KotlinIntegrationFlowDefinition.publishSubscribe()`
for a `BroadcastCapableChannel` and `vararg` of `KotlinIntegrationFlowDefinition` builders.
This allows us to not introduce a `BroadcastPublishSubscribeSpec` wrapper for Kotlin
and let us to remove `publishSubscribeChannel()` DSL methods for `PublishSubscribeSpec`
since it is covered with the `publishSubscribe(PublishSubscribeChannel())` and
respective set of sub-flows in Kotlin DSL as subscribers
* Use new Kotlin specs in the `KotlinIntegrationFlowDefinition` instead of their
Java variants
* * Mention `kotlin-dsl.adoc` in the ToC
* Fix JsonToObjectTransformer for ClassNotFoundEx
Related to https://github.com/spring-projects/spring-integration/issues/3223
The `JsonToObjectTransformer` consults `JsonHeaders` first and tries to build
a `ResolvableType` from other type headers which may be just a string identifications.
In this case a `ClassNotFoundException` could be thrown if a `ResolvableType` cannot
be build against non-class identificators
* Add `valueTypeExpression` option to the `JsonToObjectTransformer` to let to
build a `ResolvableType` using any possible custom logic, e.g. resolving
target classes from some registry using their ids from the mentioned headers
**Cherry-pick to 5.2.x**
* * Fix English language mistakes
* Upgrade to Spring Data Moore-SR6
* Fix `TransactionHandleMessageAdvice` and `TransactionInterceptorBuilder`

* Messaging Annotations: process ReactiveMH
* Add support for `ReactiveMessageHandler` as a `@ServiceActivator` bean
* Wrap `ReactiveMessageHandler` in the `ReactiveMessageHandlerAdapter`
in the `ServiceActivatorAnnotationPostProcessor`
* Unwrap `ReactiveMessageHandlerAdapter` in the `AbstractMethodAnnotationPostProcessor`
for `ReactiveStreamsConsumer`
* * Add documentation for the `ReactiveMessageHandler`
& Reactive MongoDb channel adapters
* Infrastructure for ReactiveMessageHandler
We have now a `ReactiveMongoDbStoringMessageHandler` which implements
a `ReactiveMessageHandler`, but not a `MessageHandler` for possible
deferred subscriptions to the returned Reactor type
We don't have a proper application context processing for this
new type of message handlers
* Change a `ConsumerEndpointFactoryBean` to apply an `MH` and `RMH`
as possible types for handler
* Introduce a `ReactiveMessageHandlerAdapter` to wrap an `RMH`
into a `MH` for synchronous calls in the regular consumer endpoints
* Wrap an `RMH` into a `ReactiveMessageHandlerAdapter` for regular
endpoints and unwrap for `ReactiveStreamsConsumer`
* Add `RMH`-based ctor into `ReactiveStreamsConsumer` for target
reactive streams composition (`flatMap()` on the `RMH`)
* Remove a `DelegatingSubscriber` from the `ReactiveStreamsConsumer`
in favor of direct calls from the `doOnSubscribe()`, `doOnComplete()`
& `doOnNext()`
* Add an `onErrorContinue()` to handle per-message errors, but don't
cancel the whole source `Publisher`
* Use `Disposable` from the `subscribe()` to cancel in the `stop()`
- recommended way in Reactor
* Use `onErrorContinue()` in the `FluxMessageChannel` instead of
`try..catch` in the `doOnNext()` - for possible `onErrorStop()`
in the provided upstream `Publisher`
* Handle `RMH` in the `ServiceActivatorFactoryBean` as a direct handler
as well with wrapping into `ReactiveMessageHandlerAdapter` for return.
The `ConsumerEndpointFactoryBean` extracts an `RMH` from the adapter
for the `ReactiveStreamsConsumer` anyway
* Add XML parsing test for `ReactiveMongoDbStoringMessageHandler`
* Add `log4j-slf4j-impl` for all the test runtime since `slf4j-api`
comes as a transitive dependency from many places
* * Fix conflicts after rebasing to master
* * Fix typo in warn message
* Change `Assert.state()` to `Assert.isTrue()`
for `ConsumerEndpointFactoryBean.setHandler()`
* * Fix `ConsumerEndpointFactoryBean` when reactive and no advice-chain
* Fix race condition in the
`ReactiveMongoDbStoringMessageHandlerTests.testReactiveMongoMessageHandlerFromApplicationContext()`
* * Handle `ReactiveMessageHandler` in Java DSL.
Essentially request a wrapping into `ReactiveMessageHandlerAdapter`.
Describe such a requirements in the `ReactiveMessageHandlerAdapter` JavaDocs
* Some Java DSL test polishing
* Add Java DSL for `ReactiveMongoDbStoringMessageHandler`
* Propagate missed `ApplicationContext` population into an internally
created `ReactiveMongoTemplate` in the `ReactiveMongoDbStoringMessageHandler`
* Remove Boon dependency and its usage
* Remove overloaded methods from the `IntegrationFlowDefinition`
- we can simply rely now on the super class
* Remove (or rework) deprecated entities in the docs
* Fix tests for removed deprecated APIs
* Rework affected tests to JUnit 5
