AbstractTransactionSynchronizingPollingEndpoint was introduced late in the 2.2 release process to avoid a breaking change to AbstractPollingEndpoint. For 3.0, its methods are now pulled-up into APE.
Further change:
* remove Deprecated Setter (PollerMetadata)
* fix failing test
Copy schemas, cleanup whitespace, update spring.schemas files,
update version in AbstractIntegrationNamespaceHandler.
For each schema compared the 2.2 version with the 3.0 version
(diff -w), ensuring the only difference is the import of
3.0 schemas (where appropriate) instead of 2.2.
The AbstractRequestHandlerAdvice uses an internal wrapper for
Throwable, in a similar fashion to the TransactionInterceptor.
Exceptions are unwrapped properly when exiting the invoke method so
callers are unaware of the wrapping.
The technique is used to avoid user errors (for example catching OOM
Errors and not propagating). User code (subclasses) only catch
Exceptions.
However, in the case of the ExpressionEvaluatingRequestHandlerAdvice,
the exception is included in any ErrorMessage sent to a failureChannel.
User code should not have to navigate these internal exceptions within
the cause tree.
Add a method to the abstract class unwrapExceptionIfNecessary, which
will unwrap the root cause exception if possible.
Add a method to the abstract class unwrapThrowableIfNecessary, which
will unwrap the root cause Throwable if possible.
Update tests to reduce the cause() traversals to reflect the
ThrowableHolderExceptions are no longer in the tree.
Add a test to verify a Throwable (such as an OOM) is properly
propagated.
Add a test to verify that when the root cause is a Throwable (and not
an Exception), the ErrorMessage sent to the failureChannel does not include
the ThrowableHolderException.

2.2.0 changed ObjectToJsonTransformr to add content-type to
simplify AMQP applications.
However, in a JMS environment, the DefaultJmsHeaderMapper attempted
to map (and failed) to map the header, emitting a warning log entry.
JMS does not allow '-' in property names.
Add code such that:
1. If the ObjectToJsonTransformer is configured to use a
content-type of an empty String (after trimming), suppress the
addition of the header to the output message. For consistency, if
the inbound message already has a content type header, and the transformer
is configured with an empty String, remove the header.
2. Change the DefaultJmsHeaderMapper to map the MessageHeaders.CONTENT_TYPE
header (content-type) to/from a JMS compliant property name (content_type).
INT-2874 PR Comments
Move constant to JmsHeaderMapper interface and rename.
Fix failing test (explicit set content-type to "").
INT-2874 Documentation Updates
Add docbook and schema documentation clarifying the behavior
of the transformer with respect to setting the `content-type`
header.
INT-2874 Polishing - Remove Header Removal
After further discussion, we decided to not remove an
existing header, if 'content-type' is set to "".
This is because there was no way to handle the case of
NOT adding a header when none present, while retaining a
header if it was already present.
added test for empty content-type attrib and no existing header (while merging)
In the BeanFactoryTypeConverter, when falling
back to a PropertyEditor (when the source is non-
String and the target is String), the setValue() and getAsText()
methods are used.
This is not thread-safe and one thread might get another's
converted value.
Synchronize the use of the PropertyEditor.
Add test, that reliably reproduces the problem, to verify the
fix.
Delegating consumer endpoints (<service-activator/> etc)
may not have both 'expression' and 'ref' attributes.
Previously, 'expression' was ignored when 'ref' was present.
- Enforce mutual exclusivity in AbstractDelegatingEndpointParser.
- Add tests for illegal combinations.
- Improve error message when 'method' used with <expression/>.
- Change parser to use reader.error() instead of Assert.
- Add element description to all parser errors.
Gradle may run tests using multiple threads.
Using shared resources (e.g. `System.out`) may produce concurrency issues.
* Remove usage of `System.out`
* Add mocking around `LoggingHandler#messageLogger`.

Heretofore there wasn't ability to make some scenario like this, when we want to make failure notification on each retry:
<service-activator>
<request-handler-advice-chain>
<bean class="org.springframework.integration.handler.advice.RequestHandlerRetryAdvice"/>
<bean class="org.springframework.integration.handler.advice.ExpressionEvaluatingRequestHandlerAdvice"
p:onFailureExpression="#exception" p:failureChannel-ref="errorOnEachRetryChannel"/>
</request-handler-advice-chain>
</service-activator>
The second Advice was invoked only once. This was because `ProxyMethodInvocation` keeps the index of current interceptor
on each `invocation.proceed()`, which is recursive by design.
So, change `AbstractRequestHandlerAdvice` to use `((ProxyMethodInvocation) invocation).invocableClone().proceed();`
This way, we get a fresh `MethodInvocation` for the current `Advice` with nested desired advices.

Jdbc Message Store always converts the correlation id

This causes reaper issues with the correlating message

This change ensures the lock is properly mutually
exclusive.
Added pseudo-tx support for Mail inbound adapters
For polling adapters no changes have been made other then returning a javax.mail.Message instead of its copy so
post-tx dispositions could be performed on it.
For Imap IDLE adapter changes are simiar to the once present in SPCA where TX synchronization logic was added to ImapIdleChannelAdapter
Couple of things to note:
First IDLE receives an array of messages while Polling task receives one message which means i need to sendMessage in the Polling task in the separate thread, so for maintaining single thread semantics we have now it uses single thread executor to send Messages
Renamed MSRH to TransactionalResourceHolder since we no longer use 'source' anywhere and in the case of IDLE there is no MessageSource. Its is truly a holder of attributes we want to make available for use (e.g., SpEL)
INT-1819 Polishing

INT-1819 Remove 'public abstract' from interface
Modifiers are not needed on an interface.
When the reaper runs, and finds a group that is in the
process of being completed, the reaper blocks on the
lock, but when the lock is released, goes ahead and
reaps the group.
Now, after obtaining the lock, the reaper checks to
see if the modified date changed and, if so, aborts
the reap of the group this time around.
Required adding lastModified accounting for SimpleMessageGroup
(accounting already exists for other message groups).
Test case reproduced the problem, demonstrating duplicate
output messages.
After the fix, it shows the reap was aborted in the debug
log.

Fix RecipientListRouterParser to extend
from AbstractRouterParser, thus eliminating
the problem described in INT-2626.
Previously, the router was a top level bean and, since
it is an @ManagedResource, the mbean exporter eagerly
instantiated it (and its Recipients) before the
ChannelInitializer ran.
Now, it is an anonymous inner bean inside a FB,
so the exporter no longer "finds" it,
thus deferring the Recipient instantiation
until the router itself is instantiated via its FB,
which will be after the C.I. runs.
This is all fine, with one caveat - previously the RLR
is made available as an MBean - now it is not,
unless you ALSO add the int-jmx:mbean-exporter.
However, the MBean is very basic, with no attributes and
a single operation 'setShouldTrack()', so the risk is
extremely low and the workaround is to add the
IntegrationMBeanExporter.
