Subject: [PATCH 05/24] Fix receiver to use pooled/cached ConnectionFactory
 when enabled

The receiver now conditionally uses the ConnectionFactory bean when it's
JmsPoolConnectionFactory or CachingConnectionFactory, otherwise creates a
dedicated ServiceBusJmsConnectionFactory. This matches the expected behavior
where the receiver should use the same pooled/cached connection factory as
the sender when those features are enabled.

Subject: [PATCH 06/24] Fix receiver to use dedicated ConnectionFactory when
 properties not set

The receiver now only uses the shared ConnectionFactory bean when pooling
or caching is EXPLICITLY enabled. When properties are not set, the receiver
creates a dedicated ServiceBusJmsConnectionFactory instance, even though
the sender defaults to CachingConnectionFactory. This matches the expected
behavior table from the issue.

Subject: [PATCH 07/24] Implement comprehensive JMS ConnectionFactory
 configuration logic

- Updated logic to follow the complete configuration table with all 9 scenarios
- Added JavaDoc tables to both sender and receiver configurations
- Added comprehensive test coverage for all scenarios
- Updated CHANGELOG with detailed configuration table and rules
- Both properties set to true now uses CachingConnectionFactory (cache takes precedence)
- Added proper fallback logic when required classes are not in classpath

 ### Breaking Changes
 
-- The default JMS ConnectionFactory for Service Bus has been changed from `ServiceBusJmsConnectionFactory` to `CachingConnectionFactory` to improve efficiency for sender operations using `JmsTemplate`. This change only affects the sender side when neither `spring.jms.servicebus.pool.enabled` nor `spring.jms.cache.enabled` properties are explicitly set. The receiver side (JMS listeners) creates a dedicated `ServiceBusJmsConnectionFactory` instance by default, and only uses the shared ConnectionFactory bean when pooling or caching is **explicitly enabled** (when `spring.jms.servicebus.pool.enabled=true` or `spring.jms.cache.enabled=true`). To revert to the previous behavior, explicitly set `spring.jms.cache.enabled=false`.
+- The default JMS ConnectionFactory for Service Bus has been changed from `ServiceBusJmsConnectionFactory` to `CachingConnectionFactory` to improve efficiency for sender operations using `JmsTemplate`. The ConnectionFactory type is determined by the following configuration properties:
+
+  | `spring.jms.servicebus.pool.enabled` | `spring.jms.cache.enabled` | Sender ConnectionFactory | Receiver ConnectionFactory |
+  |--------------------------------------|----------------------------|--------------------------|----------------------------|
+  | not set                              | not set                    | CachingConnectionFactory | ServiceBusJmsConnectionFactory |
+  | not set                              | true                       | CachingConnectionFactory | CachingConnectionFactory |
+  | not set                              | false                      | ServiceBusJmsConnectionFactory | ServiceBusJmsConnectionFactory |
+  | true                                 | not set                    | JmsPoolConnectionFactory | JmsPoolConnectionFactory |
+  | true                                 | true                       | CachingConnectionFactory | CachingConnectionFactory |
+  | true                                 | false                      | JmsPoolConnectionFactory | JmsPoolConnectionFactory |
+  | false                                | not set                    | CachingConnectionFactory | ServiceBusJmsConnectionFactory |
+  | false                                | true                       | CachingConnectionFactory | CachingConnectionFactory |
+  | false                                | false                      | ServiceBusJmsConnectionFactory | ServiceBusJmsConnectionFactory |
+
+  **Rules:**
+  1. If only one property (`spring.jms.servicebus.pool.enabled` or `spring.jms.cache.enabled`) is set to true, both sender and receiver use that ConnectionFactory type.
+  2. If both properties are set to true, `CachingConnectionFactory` takes precedence for both sender and receiver.
+  3. If `spring.jms.cache.enabled` is set to false, `ServiceBusJmsConnectionFactory` or `JmsPoolConnectionFactory` is used based on `spring.jms.servicebus.pool.enabled`.
+  4. Default (no properties set or `pool.enabled=false`): sender uses `CachingConnectionFactory`, receiver uses `ServiceBusJmsConnectionFactory`.
+  5. When using `CachingConnectionFactory` or `JmsPoolConnectionFactory`, the related class must be in the classpath. If not present, it falls back to `ServiceBusJmsConnectionFactory`.

Subject: [PATCH 09/24] Address code review feedback - improve fallback logic
 and prevent duplicate instances

1. Fixed sender fallback logic: When a factory is explicitly requested but classes
   are missing, immediately fallback to ServiceBusJmsConnectionFactory instead of
   trying other factories.

2. Fixed receiver to memoize dedicated ConnectionFactory: Use double-checked
   locking to ensure only one ServiceBusJmsConnectionFactory instance is created
   and shared between both listener container factories.

3. Improved tests: Added proper fallback tests that explicitly request pooling/
   caching but filter out the required classes to validate real fallback behavior.

Subject: [PATCH 10/24] Simplify receiver ConnectionFactory memoization pattern

Use synchronized method with null-check instead of static holder pattern
since the factory needs instance-specific properties. This is simpler,
thread-safe, and addresses code review concerns about lazy initialization.

 ### Breaking Changes
 
-- The default JMS ConnectionFactory for Service Bus has been changed from `ServiceBusJmsConnectionFactory` to `CachingConnectionFactory` to improve efficiency for sender operations using `JmsTemplate`. The ConnectionFactory type is determined by the following configuration properties:
-
-  | `spring.jms.servicebus.pool.enabled` | `spring.jms.cache.enabled` | Sender ConnectionFactory | Receiver ConnectionFactory |
-  |--------------------------------------|----------------------------|--------------------------|----------------------------|
-  | not set                              | not set                    | CachingConnectionFactory | ServiceBusJmsConnectionFactory |
-  | not set                              | true                       | CachingConnectionFactory | CachingConnectionFactory |
-  | not set                              | false                      | ServiceBusJmsConnectionFactory | ServiceBusJmsConnectionFactory |
-  | true                                 | not set                    | JmsPoolConnectionFactory | JmsPoolConnectionFactory |
-  | true                                 | true                       | CachingConnectionFactory | CachingConnectionFactory |
-  | true                                 | false                      | JmsPoolConnectionFactory | JmsPoolConnectionFactory |
-  | false                                | not set                    | CachingConnectionFactory | ServiceBusJmsConnectionFactory |
-  | false                                | true                       | CachingConnectionFactory | CachingConnectionFactory |
-  | false                                | false                      | ServiceBusJmsConnectionFactory | ServiceBusJmsConnectionFactory |
-
-  **Rules:**
-  1. If only one property (`spring.jms.servicebus.pool.enabled` or `spring.jms.cache.enabled`) is set to true, both sender and receiver use that ConnectionFactory type.
-  2. If both properties are set to true, `CachingConnectionFactory` takes precedence for both sender and receiver.
-  3. If `spring.jms.cache.enabled` is set to false, `ServiceBusJmsConnectionFactory` or `JmsPoolConnectionFactory` is used based on `spring.jms.servicebus.pool.enabled`.
-  4. Default (no properties set or `pool.enabled=false`): sender uses `CachingConnectionFactory`, receiver uses `ServiceBusJmsConnectionFactory`.
-  5. When using `CachingConnectionFactory` or `JmsPoolConnectionFactory`, the related class must be in the classpath. If not present, it falls back to `ServiceBusJmsConnectionFactory`.

Subject: [PATCH 16/24] Fix lifecycle management and add receiver
 ConnectionFactory tests

1. Fixed CHANGELOG typo: Removed extra comma after "Note:"
2. Added lifecycle management: Implemented DisposableBean to properly close
   dedicated ConnectionFactory instances on shutdown
3. Memoized all dedicated factory types: Added volatile fields and synchronized
   getter methods for CachingConnectionFactory, JmsPoolConnectionFactory, and
   ServiceBusJmsConnectionFactory to prevent duplicate instances
4. Added receiver tests: Added 4 comprehensive tests verifying receiver uses
   correct ConnectionFactory type in different configuration scenarios

This ensures proper resource cleanup and validates receiver behavior.

Subject: [PATCH 17/24] Enhance receiver tests to verify actual
 ConnectionFactory types

1. Fixed CHANGELOG typo: Removed extra comma after "Note:"
2. Enhanced receiver tests to verify actual ConnectionFactory instances:
   - Create DefaultMessageListenerContainer from factories
   - Assert ConnectionFactory type using getConnectionFactory()
   - Verify dedicated instances are NOT same as sender bean
   - Verify shared beans ARE same as sender bean
   - Verify both listener containers share same dedicated instance (memoization)

Tests now properly validate that receiver uses correct ConnectionFactory type
and that memoization prevents duplicate instances.

Subject: [PATCH 19/24] Extract shared helper method and improve type assertion
 in integration test

1. Extracted createServiceBusJmsConnectionFactory() to a static package-level
   helper method in ServiceBusJmsConnectionFactoryConfiguration to avoid code
   duplication between sender and receiver configurations.

2. Updated integration test to use assertInstanceOf instead of assertSame for
   class type checking, which is more robust for Spring beans that may be proxied.

This prevents future divergence between sender/receiver creation paths and makes
tests less brittle.

Subject: [PATCH 20/24] Remove hard references to optional dependencies to
 prevent NoClassDefFoundError

Changed field types from concrete ConnectionFactory types (CachingConnectionFactory,
JmsPoolConnectionFactory) to ConnectionFactory interface. Use reflection and class
name checks to avoid NoClassDefFoundError when optional dependencies (pooled-jms,
spring-boot-jms) are not present on the classpath.

Changes:
1. Changed volatile fields to ConnectionFactory type
2. Removed imports of CachingConnectionFactory, JmsPoolConnectionFactory, and
   JmsPoolConnectionFactoryFactory
3. Added helper methods using class name string comparison instead of instanceof
4. Use reflection to create and configure factory instances
5. Use reflection in destroy() method to call cleanup methods

This ensures the class loads successfully even when optional dependencies are
missing, with graceful degradation to ServiceBusJmsConnectionFactory.

Subject: [PATCH 21/24] Fix compilation error by removing hard reference to
 JmsProperties.Pool

Changed line 154 to use Class.forName for JmsProperties$Pool instead of
directly referencing JmsProperties.Pool.class. This removes the last hard
reference to an optional dependency class that was causing compilation failure.

The inner class Pool is loaded reflectively as "JmsProperties$Pool" which is
the standard way to reference inner classes in reflection.

Subject: [PATCH 22/24] Add logging to ConnectionFactory cleanup catch blocks

Added LOGGER.warn statements in the destroy() method catch blocks to log
cleanup failures instead of silently ignoring them. This provides visibility
into any issues during application shutdown while still allowing graceful
shutdown to continue.

Subject: [PATCH 24/24] Fix incorrect class name in JmsPoolConnectionFactory
 reflection

Changed Class.forName from "JmsProperties$Pool" to "JmsPoolConnectionFactoryProperties"
which is the correct type expected by JmsPoolConnectionFactoryFactory constructor.
This matches the usage in ServiceBusJmsConnectionFactoryConfiguration where
serviceBusJmsProperties.getPool() returns JmsPoolConnectionFactoryProperties.
