If there are no records to receive, the poll blocked for `20*pollTimeout`.
Wake the consumer during partition assignment; however, this changes the behavior
when there are records present - the first poll always returns no records.
Detect that the wakeup was due to assignment and perform another poll.
Also add some debug logging, and don't create a new consumer if the source was
stopped.
**cherry-pick to 5.4.x**
* To align with the rest of Spring portfolio, based on Spring Framework 5.3.x generation,
it is better to upgrade to the Kotlin version supported by SF
* Fix `ClassUtils.isLambda()` to treat `$inlined$` classes as Kotlin lambdas and let
Java DSL to delegate to the `LambdaMessageProcessor` for better expected type handling.
Looks like Kotlin does not carry type info in its lambdas anymore (at least for functions).
* Add `-parameters` to the compiler args for possible method argument names discovery.
Essentially realign with the rest of portfolio
* Fix Kotlin tests for deprecated API
Spring for Apache Kafka 2.8 has introduced an new `CommonErrorHandler`
and deprecated its retying components including `RetryingMessageListenerAdapter`.
* For proper compatibility with `spring-kafka-2.8.0`, which is going to be
a foundation for upcoming Spring Boot 2.6, it is better to suppress deprecations
and don't raise such a concern to end-users.
In the future we will revise retrying logic to expected behavior from `spring-kafka-2.8.0`.
Or will do home-made one as it is now with `AmqpInboundChannelAdapter`, for example.

Previously, the `KafkaProducerMessageHandler` did not synchronize a transaction
with some other transaction (e.g. JDBC); it published in a local transaction instead.
Also configure the Gradle Kotlin Daemon to work with JDK 16.
**cherry-pick to 5.4.x**
* Fix compatibility with upgraded dependencies
* Move `What's New` for `5.4` to `history`
* Add `XmlUnit` dependency since the latest AssertJ has deprecated its `isXmlEqualTo()`
* Remove `javax.annotation-api` and `apiguardian-api` as redundant dependencies
* 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
Currently, the only way to block is to set `sync=true` which waits for the future.
The problem with this is it only supports one-at-a-time publication.
Add an option to send the send futures to a channel, allowing the application to
send multiple records and then wait on the futures later.
Also fix long-running test.
* Add docs.
The `pause` variable is set in the container already after a `consumer.pause()` call.
Therefore it's state might not be changed after acquiring the latch from the mock answer
* Remove redundant `@SuppressWarnings("deprecation")`
* Add `Duration.ofSeconds(10)` to `StepVerifier.verify()`
to avoid infinite wait and lose failing text context on the hang CI build
- Simplify MBeans - instead of wrapping to expose lifecycle methods,
implement `ManageableLifecycle`. Register an additional MBean for
polled endpoints to control the lifecycle.
* Polishing
- Move `QueueChannel` `@ManagedAttribute`s to `QueueChannelOperations`
- Make all `AbstractEndpoints` `IntegrationManagedResource`s and remove `ManagedEndpoint`
to allow exposure of any `@Managed*` methods (including those on `Pausable`)
- Revert to `Lifecycle` for classes that are not related to endpoints
- Remove legacy metrics from docs
- merge master branch from old repo (`git-filter-repo`) for src branch
- update build.gradle
- copy docs from Spring for Apache Kafka Chapter
Doc polishing.
Fix http: references in tests.
* Add `What's New` note and fix `polling-consumer.adoc`
not linking to external project any more
* Rename schema
* Upgrade to Gradle 6.3-rc-3 for transitive dependency fix.
* Remove version from schema; polish `build.gradle` to remove unneeded features.
