When we register `IntegrationFlow` s concurrently at runtime, we may end up with the problem when we register the same object with the same bean name, but in different places. Or when we turn off bean overriding, we end up with the exception that bean with the name already registered * Wrap `IntegrationFlow` bean registration in the `StandardIntegrationFlowContext` into the `Lock` when its bean name is generating * Make `StandardIntegrationFlowContext.registry` as `ConcurrentHashMap` to avoid `ConcurrentModificationException` during `put()` and `remove()` * Fix concurrency for beans registration with the generation names in the `IntegrationFlowBeanPostProcessor` using an `IntegrationFlow` id as a prefix for uniqueness. **Cherry-pick to 5.0.x** Fix generated bean name in the WebFluxDslTests Use only single `Lock` in the `StandardIntegrationFlowContext`: we don't need a fully blown `LockRegistry` there anymore since we have only one synchronization block there and it is always around the same type * Add `What's New` note, and mention changes in the `dsl.adoc` Minor doc polishing.
Spring Integration

Checking out and Building
To check out the project and build from source, do the following:
git clone git://github.com/spring-projects/spring-integration.git
cd spring-integration
./gradlew build
NOTE: While Spring Integration runs with Java SE 6 or higher, a Java 8 compiler is required to build the project.
If you encounter out of memory errors during the build, increase available heap and permgen for Gradle:
GRADLE_OPTS='-XX:MaxPermSize=1024m -Xmx1024m'
To build and install jars into your local Maven cache:
./gradlew install
To build api Javadoc (results will be in build/api):
./gradlew api
To build reference documentation (results will be in build/reference):
./gradlew reference
To build complete distribution including -dist, -docs, and -schema zip files (results will be in build/distributions)
./gradlew dist
Using Eclipse
To generate Eclipse metadata (.classpath and .project files), do the following:
./gradlew eclipse
Once complete, you may then import the projects into Eclipse as usual:
File -> Import -> Existing projects into workspace
Browse to the 'spring-integration' root directory. All projects should import free of errors.
Using IntelliJ IDEA
To generate IDEA metadata (.iml and .ipr files), do the following:
./gradlew idea
