JIRA: https://jira.spring.io/browse/INT-4466 When we schedule group for force complete in the `AbstractCorrelatingMessageHandler`, we don't track a group `timestamp` and its `lastModified` before the scheduled task. This way, in the cluster environment, we may schedule several tasks for different messages and the first started may release the group too early. Just because we extract a `MessageGroup` from the store already in the task per se. * Propagate the actual `timestamp` and `lastModified` from group before scheduling task. Compare these value with the actual group metadata in the `processForceRelease()` before performing real `forceRelease()`. This way we restore behavior before fixing memory leak, when we propagated full `MessageGroup` to the scheduled task * Implement `ResequencingMessageHandler.getComponentType()` for consistency * Remove unnecessary overhead with the `volatile` on many `AbstractCorrelatingMessageHandler` properties, which hardly ever can be changed at runtime **Cherry-pick to 5.0.x and 4.3.x**
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
