This is not thread safe - another thread could end up with a null channel resolver before the current thread assigns it.
Since the code under the condition is idempotent, it is ok for multiple threads to execute it. Set to true after the work is done.

Yeah... I questioned myself why in other place we use boolean flag instead of this AtomicBoolean.
Thank you! 😄
Fixes spring-projects#3945 The `IntegrationManagementConfiguration` produces an `IntegrationManagementConfigurer` which is a `BeanPostProcessor`. According to Spring recommendation this kind of infrastructure beans must be declared as `static`. Due to an `implements ImportAware, EnvironmentAware` nature of the `IntegrationManagementConfiguration`, we cannot use `static @Bean` method. But since the `IntegrationManagementConfiguration` is not involved in any bean post-processing, it is safe to follow recommendation and mark it as a `@Role(BeanDefinition.ROLE_INFRASTRUCTURE)`. * Fix `MessagePublishingInterceptor` to initialize `MessagingTemplate` and `DestinationResolver` lazily * Fix `AbstractMethodAnnotationPostProcessor` to initialize `DestinationResolver` lazily **Cherry-pick to `5.5.x`**
…ionPostProcessor` instead of direct property access which might not be initialized yet * Use a plain `boolean` for `templateInitialized` in the `MessagePublishingInterceptor` to avoid skips in other thread where and move on with still not initialized properties

Cherry-pick is not clean - please back port. |
