* 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.
* Added support for header-mapper to outbound-channel-adapter and
outbound-gateway XML
* Follow up on review
* Corrected mistake
* Corrected indentation
