* Enable ModifierOrderCheck Checkstyle rule
* Fix violations for `static` and `abstract` modifier
* Remove redundant code in the `TcpNioConnection`
* Mark `connectionFactoryName` as `@Nullable` in the `TcpConnectionSupport`
ctor and its inheritors
* Fix some smells according IDEA suggestions in the affected classes
* This should fix some Sonar smells as well
* * Fix `HeaderMapperTests`
* * Polishing `TcpConnection` code style and fix Javdocs
* INT-4569: Disallow beans override in DSL
JIRA: https://jira.spring.io/browse/INT-4569
* Thorw `BeanDefinitionOverrideException` from the
`IntegrationFlowBeanPostProcessor` when it detects existing bean and it
is not the same object we try to register from the DSL
* Document limitations about `prototype` beans
* Some polishing in the DSL chapter of the docs
* * Fix algorithm in the `IntegrationFlowBeanPostProcessor.noBeanPresentForComponent()`
* * Polishing dsl.adoc
* Call `BeanFactory.initializeBean()` for existing beans if they are
`prototype`
* * Code formatting in the `ManualFlowTests`
* RedisLock: Throw exception from unlock on expire
The lock might be expired in target Redis store in between `lock()` and
`unlock()`.
So, throw an `IllegalStateException` when lock is expired during
unlocking.
At the same time the lock lock is unlocked anyway.
**Cherry-pick to 5.0.x**
* * Create a new test for exception
* Add more info into the exception
* Use Context CL wherever it is applicable
* Use `ClassUtils.getDefaultClassLoader()` in the `IntegrationManagementConfigurer`
for checking a Micrometer presence from the `afterSingletonsInstantiated()`
* Use `ClassUtils.getDefaultClassLoader()` in the `ScatterGatherHandler`
to load required class
* Refactor `HeaderEnricherParserSupport` do not use CL at all.
The `TypedStringValue` will resolve a target type later by the
`BeanFactory`.
This way we honor a property placeholder behavior for the `type` XML
attribute
* * Use `ClassUtils.getDefaultClassLoader()` in the ScatterGatherHandler ctor

The `ImapMailReceiverTests` fails sporadically according some race
condition or wrong logic.
* Fix `ImapIdleChannelAdapter` to check for folder not null before
performing logic in the `IdleTask`
* Polishing for logs which are based on constant strings
* Remove `volatile` from configuration properties in the
`ImapIdleChannelAdapter` and `AbstractMailReceiver`
* Refactor some smells into the `protected` getters instead of direct
access to the property
* Stop channel adapters in the `ImapMailReceiverTests`
* Also destroy task schedulers in the `ImapMailReceiverTests`
* INT-4565: Fix IntComponentScan for profiles
JIRA: https://jira.spring.io/browse/INT-4565
* Propagate an `Environment` to the internal `ClassPathScanningCandidateComponentProvider`
in the `IntegrationComponentScanRegistrar` for proper profiles activation
* Ensure the logic works in the `GatewayInterfaceTests`
* Some polishing and performance improvement for the `GatewayInterfaceTests`
* Add a note about `@Profile` in the `gateway.adoc`
* Polishing for the `gateway.adoc`
**Cherry-pick to 5.0.x & 4.3.x**
* * Add not activated by profile gateway interface into the `GatewayInterfaceTests`
* More `GatewayInterfaceTests` polishing
* Fix typo in the `gateway.adoc`
* Fix Checkstyle violation
JIRA: https://jira.spring.io/browse/INT-4150
* Fix internal `taskScheduler` for destroy in the `ImapMailReceiver`
* Some code style polishing in the `ImapIdleChannelAdapter`
JIRA: https://jira.spring.io/browse/INT-4563
* Add a `MqttDslTests` with the JMX configured to be sure that SI
managed components are registered in JMX properly.
* Also this test covers a Java DSL configuration for MQTT channel adapters
* Some polishing for `AbstractMqttMessageHandler`
* Document Java DSL configuration for the MQTT channel adapters
JIRA: https://jira.spring.io/browse/INT-4564
INT-4550 added an error log when multiple ACMHs were registered with the
same store; the error log logic was incorrect and the error was logged
when the first ACMH was registered.
JIRA: https://jira.spring.io/browse/INT-4385
It is slightly unclear for end-users that `<jms:listener-container/>`
is just a syntax sugar and the real JMS container is created by the
`<jms:listener>` sub-element
* Add a NOTE to the `jms.adoc` to explain such a confuse and what and
how is going to happen if the intention to use a `<jms:listener-container/>`
for Spring Integration channel adapters.
* Fix ambiguity in the `JpaExecutor`
Since we can't mutate a provided `ParameterSourceFactory` with the
provided `jpaParameters`, we have to reject such a combined
configuration in favor of the advice to configure params on the
provided `ParameterSourceFactory`
* Throw `IllegalStateException` when `ParameterSourceFactory` and
`jpaParameters` are configured together on the `JpaExecutor`
* Some refactoring for `JpaExecutor` to have a consistent code style
* Fix tests according new logic
* Document such an ambiguity configuration to avoid confusion
**Cherry-pick to 5.0.x**
* * Use `assertThatThrownBy()` in the `JpaExecutorTests`
* Fix "No BeanFactory" warning in the `JpaExecutorTests`
* * Resolve potential NPE and add `@NonNullApi` with `@Nullable` on the `poll()`
JIRA: https://jira.spring.io/browse/INT-4556
We definitely need to resolve a `@Bean` method to the target object to
be sure do not create a new `MessageHandler` bean.
**Cherry-pick to 5.0.x**
