* Upgrade to Checkstyle `7.1`
* Relax `RequireThis` rule a bit. Right now it does the effort only in case of overlapping. See https://github.com/checkstyle/checkstyle/issues/2362 for more info
* Enable some annotation rules and provide fixes for violations
* Enable `tabs indents` rule. This was the biggest fix in this PR
* Resolve `TODO` in the `MessagingMethodInvokerHelper` and fix tests to meet `IllegalStateException` now
Remain Checkstyle version `6.16.1` and reinstate `RequireThis` rule
The latest Checkstyle has a bug with local scope variables if they have the same names as property.
Revert some literals splitting
Fix some line length exceeding and code style
* Fix several typos in log messages. And some test on the matter as well
* Add comment to `AbstractPersistentAcceptOnceFileListFilter.rollback()` to clarify the reason of `rollingBack` variable
* Make `RemoteFileTemplate.StreamHolder` as `static` to avoid extra internal variable to outer class instance
* Replace `MessagingException` with `AbstractInboundFileSynchronizingMessageSource` in `init()` method of some components. It isn't Messaging yet in that phase
* Fix `SubscribableRedisChannel.MessageListenerDelegate` to handle `Object` not `String`, because with the `serializer` injection there is no guaranty that incoming is always `String`
* Move `JSch.setLogger(new JschLogger());` in the `DefaultSftpSessionFactory` to `static` block. It really should be done only once
* Remove `Assert.isTrue(this.port >= 0)` from the `DefaultSftpSessionFactory`. The subsequant `initJschSession()` convert it to default `22` port
* Change in the `JschProxyFactoryBean` `UnsupportedOperationException` to `IllegalArgumentException`. Wrong enum is wrong argument. That isn't a problem of operation
* Simplify `stop()` in the `CuratorFrameworkFactoryBean` and mark it as a `this.running = false`. Otherwise it wasn't able to be restarted
* Expose `leaderEventPublisher` in the `LeaderInitiatorFactoryBean` and fix `stop(Runnable callback)` with propagation `callback` to delegate.
Fix `SubscribableRedisChannelTests` for new `handleMessage(Object)` signature
JIRA: https://jira.spring.io/browse/INT-4075
Fixes GH-1854 (https://github.com/spring-projects/spring-integration/issues/1854)
The `catch` block just swallows an Exception with the logger and leaves `stompSessionListenableFuture` as `null`.
The next `stompSessionListenableFuture` usage over two code lines bellow ends up with `NPE`.
* Add reconnect logic into that `catch` block and just return from there, since we don't have anything to go ahead.
* Add `if (e != null) {` around `log.error` in the `scheduleReconnect`
* Add `if...else` around `this.stompClient.getTaskScheduler()` and `log.info()` to notify end-user that there won't be reconnection if there is no `taskScheduler`
* Add `StompSessionManagerTests` mock tests to verify solution
**Cherry-pick to 4.2.x**

The wrong method `WebSocketStompClient.connect()` has been used before because of `Object` vararg.
* Fix to the proper method invocation
* Modify `StompInboundChannelAdapterWebSocketIntegrationTests` with `origin` handshake header to prove the fix
* `gradlew clean check -x test --parallel --continue` - to collect reports
* `gradlew fixThis --parallel` - to fix all possible vulnerabilities. With `-Dfile.encoding=UTF-8` on Windows
Since the `RequireThisCheck` doesn't see parents for anonymous classes (e.g. `Runnable` callback), its report doesn't contains the outer class name with `this.`,
therefore we still have to fix those cases manually.
Thanks to the wrong `replacer` just with `this.` we have uncompilable code enough easy to find problems.
Not so easy to fix for good readability though...
* Upgrade to Grade 2.12
* Upgrade to SonarQube native plugin
The fix contains at about 300 files. So, will be done on merge.

The `StompMessageHandler` synchronized on the `sessionHandler` during `connectIfNecessary()`
performing mutually exclusive connect operation in the `StompSessionManager`.
Since the last one synchronizes on all `sessionHandler`s during its own operations, we end up with the deadlock
waiting for the `connectSemaphore`.
Change synchronization monitor object to the `connectSemaphore` accomplishing the same desired mutually exclusive connect logic
in the `StompMessageHandler`.

Some test classes (e.g. `TestUtils`) were duplicated in core to avoid cyclic
dependency.
Now that core messaging has been moved to spring-messaging, it is possible
to remove the dependencies on `spring-integration-core` from `spring-integration-test`.
A few minor test cases have been moved to `spring-integration-core`.
The simple polishing to the `build.gradle` and `ServiceActivatorOnMockitoMockTests`
JIRA: https://jira.spring.io/browse/INT-3895
* `@Ignore` `DelayerUsageTests.testDelayWithCustomScheduler()` as very weak test. (We can consider it to remove at all: doesn't test anything from our side)
* Add `LogAdjustingTestSupport` diagnostic to the `OutboundGatewayFunctionTests`
Tentative commit to see more logs from Travis
Additional diagnostics

Note sure yet what race condition we have in the `DefaultSubscriptionRegistry`,
but that looks for me better to follow with the standard `SubscriptionRegistry.findSubscriptions()`
to check subscription present, unless fail during `send()` because of `destinationLookup` early exit.
Fix for the `StompServerIntegrationTests`
Looks like we have to `reconnect()` for any `handleTransportError()` activity,
otherwise we are just hang in the Reactor's TCP reconnect loop without freeing resources
for other activities, e.g. start Embedded STOMP Broker.
Increase `receive` timeout in case of wait for the Broker Start
* `ClientWebSocketContainer`: add some synchronization to avoid race conditions: https://build.spring.io/browse/INT-B41-492
* `TomcatWebSocketTestServer`: convert to `0` port to rely on the OS resolution for `localPort`
* Add `LogAdjustingTestSupport` for STOMP test
* `SftpServerTests`: use `0` port to rely on the OS resolution for `localPort`
* `ImapMailReceiver`, `OutboundGatewayFunctionTests` (JMS), `CachingClientConnectionFactoryTests`,
`AsyncGatewayTests`, `AsyncMessagingTemplateTests`, `GatewayParserTests`, `PriorityChannelTests`, `AggregatorIntegrationTests`: increase timeout
* `EnableIntegrationTests`: use `LogAdjustingTestSupport`
* `FileOutboundChannelAdapterParserTests`: rework `Thread.sleep()` with `CountDownLatch`
* `ConnectionToConnectionTests`: increase timeout and count iteration. Previously with `1sec` we may lose some events. And we can't just rely on the `10sec`,
because the last iteration will be so long
* `TcpOutboundGatewayTests`: `500ms` is so big timeout to wait for the `Exception` that in the high load environment we can yield to other Thread so long.
Like in our case to `server` Thread to send the reply for us. Therefore decrease the Exception timeout to the `50ms` and increase server delay to `2sec`
* `StompInboundChannelAdapterWebSocketIntegrationTests`: remove `@Qualifier("taskScheduler")` as a potential candidate to test against latest SF changes.
We're fine with `SF-4.2.2` and it is just a test-case. So, I don't see reason to wait for their fix here.

Since some target application could inject there is `EvaluationContext` before, removal of
`setIntegrationEvaluationContext()` is breaking change.
This fix reverts all those setters.
JIRA: https://jira.spring.io/browse/INT-3749
Since `IntegrationEvaluationContextAware` isn't so "context-free" resource like `BeanFactory`
and `ApplicationContext`, but just a specific bean in the context, we can't follow with `BeanPostProcessor` logic - bad architecture by level of responsibility.
Therefore we should follow with standard Dependency Injection mechanism to retrieve `evaluationContext` for the particular component.
Since we can't rely on the `@Autowired` because SI can be used from the raw XML configuration,
we use utility method instead. The pattern to get the proper `integrationEvaluationContext` is:
```
@Override
protected void onInit() throws Exception {
super.onInit();
this.evaluationContext = ExpressionUtils.createStandardEvaluationContext(getBeanFactory());
}
```
JIRA: https://jira.spring.io/browse/INT-3685
* Add `StompInboundChannelAdapter` to subscribe to STOMP destination and receive messages from them.
Destinations can be added/removed (hence subscribed/unsubscribed) at runtime.
* Add `stompMessageHandler` to the send messages to STOMP destinations.
* `destination` can be extracted from `MessageHeaders`, the `destination` and `destinationExpression` are also supported.
* `RECEIPT` Frame is also supported and emitted as `StompReceiptEvent`
* `StompExceptionEvent` is emitted when we have a `failure` for `CONNECT` Frame or as a reaction to the `ERROR` Frame.
* Introduce `StompSessionManager` abstraction to manage the single `StompSession` and allow to share it between different adapters.
* Add `WebSocketStompSessionManager` implementation over `WebSocketStompClient`
* Add `Reactor2TcpStompSessionManager` implementation for target Broker connections
* Add `StompHeaderMapper`
